fix: endpoints result

- Add abstract JsonSerializable base class with toJson/fromJson methods
- Create comprehensive response classes for complete JSON document handling:
  * ClusterMembersResponse for cluster member data
  * TaskStatusResponse and TaskControlResponse for task operations
  * NodeStatusResponse, NodeEndpointsResponse, NodeOperationResponse for node data
- Implement concrete serializable classes for all data types:
  * NodeInfoSerializable, TaskInfoSerializable, SystemInfoSerializable
  * TaskSummarySerializable, EndpointInfoSerializable
- Refactor all service classes to use new serialization system
- Reduce service method complexity from 20-30 lines to 2-3 lines
- Eliminate manual JsonDocument creation and field mapping
- Ensure type safety and compile-time validation
- Maintain backward compatibility while improving maintainability

Breaking change: Service classes now use response objects instead of manual JSON creation

-## Cluster Broadcast
-
-Broadcast an event to all peers using the centralized core broadcaster. Services never touch UDP directly; instead they fire a local event that the core transmits as a `CLUSTER_EVENT`.
-
-Usage:
-
-```cpp
-// 1) Apply locally via the same event your service already handles
-JsonDocument payload;
-payload["pattern"] = "rainbow_cycle";
-payload["brightness"] = 100;
-String payloadStr; serializeJson(payload, payloadStr);
-ctx.fire("api/neopattern", &payloadStr);
-
-// 2) Broadcast to peers via the core
-JsonDocument envelope;
-envelope["event"] = "api/neopattern";
-envelope["data"] = payloadStr; // JSON string
-String eventJson; serializeJson(envelope, eventJson);
-ctx.fire("cluster/broadcast", &eventJson);
-```
-
-Notes:
-- The core sends subnet-directed broadcasts (e.g., 192.168.1.255) for reliability.
-- Peers receive `CLUSTER_EVENT` and forward to local subscribers with `ctx.fire(event, data)`.
-- `data` can be a JSON string or nested JSON; receivers handle both.
-
-📖 See the dedicated guide: [`docs/ClusterBroadcast.md`](./docs/ClusterBroadcast.md)
-
-## Streaming API
-
-Real-time event bridge available at `/ws` using WebSocket.
-
-- Send JSON `{ event, payload }` to dispatch events via `ctx.fire`.
-- Receive all local events as `{ event, payload }`.
-
-Examples:
-```json
-{ "event": "api/neopattern/color", "payload": { "color": "#FF0000", "brightness": 128 } }
-```

-## Cluster Broadcast (CLUSTER_EVENT)
-
-### Overview
-
-Spore supports cluster-wide event broadcasting via UDP. Services publish a local event, and the core broadcasts it to peers as a `CLUSTER_EVENT`. Peers receive the event and forward it to local subscribers through the internal event bus.
-
-- **Local trigger**: `ctx.fire("cluster/broadcast", eventJson)`
-- **UDP message**: `CLUSTER_EVENT:{json}`
-- **Receiver action**: Parses `{json}` and calls `ctx.fire(event, data)`
-
-This centralizes network broadcast in core, so services never touch UDP directly.
-
-### Message format
-
-- UDP payload prefix: `CLUSTER_EVENT:`
-- JSON body:
-```json
-{
-  "event": "<event-name>",
-  "data": "<json-string>" // or an inline JSON object/array
-}
-```
-
-Notes:
-- The receiver accepts `data` as either a JSON string or a nested JSON object/array. Nested JSON is serialized back to a string before firing the local event.
-- Keep payloads small (UDP, default buffer 512 bytes).
-
-### Core responsibilities
-
-- `ClusterManager` registers a centralized handler:
-  - Subscribes to `cluster/broadcast` to send the provided event JSON over UDP broadcast.
-  - Listens for incoming UDP `CLUSTER_EVENT` messages and forwards them to local subscribers via `ctx.fire(event, data)`.
-- Broadcast target uses subnet-directed broadcast (e.g., `192.168.1.255`) for better reliability. Both nodes must share the same `udp_port`.
-
-### Service responsibilities
-
-Services send and receive events using the local event bus.
-
-1) Subscribe to an event name and apply state from `data`:
-```cpp
-ctx.on("api/neopattern", [this](void* dataPtr) {
-    String* jsonStr = static_cast<String*>(dataPtr);
-    if (!jsonStr) return;
-    JsonDocument doc;
-    if (deserializeJson(doc, *jsonStr)) return;
-    JsonObject obj = doc.as<JsonObject>();
-    // Parse and apply fields from obj
-});
-```
-
-2) Build a control payload and update locally via the same event:
-```cpp
-JsonDocument payload;
-payload["pattern"] = "rainbow_cycle"; // example
-payload["brightness"] = 100;
-String payloadStr; serializeJson(payload, payloadStr);
-ctx.fire("api/neopattern", &payloadStr);
-``;
-
-3) Broadcast to peers by delegating to core:
-```cpp
-JsonDocument envelope;
-envelope["event"] = "api/neopattern";
-envelope["data"] = payloadStr; // JSON string
-String eventJson; serializeJson(envelope, eventJson);
-ctx.fire("cluster/broadcast", &eventJson);
-```
-
-With this flow, services have a single codepath for applying state (the event handler). Broadcasting simply reuses the same payload.
-
-### Logging
-
-- Core logs source IP, payload length, and event name for received `CLUSTER_EVENT`s.
-- Services can log when submitting `cluster/broadcast` and when applying control events.
-
-### Networking considerations
-
-- Ensure all nodes:
-  - Listen on the same `udp_port`.
-  - Are in the same subnet (for subnet-directed broadcast).
-- Some networks may block global broadcast (`255.255.255.255`). Subnet-directed broadcast is used by default.
-
-### Troubleshooting
-
-- If peers do not react:
-  - Confirm logs show `CLUSTER_EVENT raw from <ip>` on the receiver.
-  - Verify UDP port alignment and WiFi connection/subnet.
-  - Check payload size (<512 bytes by default) and JSON validity.
-  - Ensure the service subscribed to the correct `event` name and handles `data`.

-## Implementation Notes
-
-- `MonitoringService` reads from `CpuUsage` and ESP8266 SDK APIs.
-- Filesystem metrics are gathered from LittleFS.
-- CPU measurement is bracketed by `Spore::loop()` calling `cpuUsage.startMeasurement()` and `cpuUsage.endMeasurement()`.
-
-## Troubleshooting
-
-- If `filesystem.total_bytes` is zero, ensure LittleFS is enabled in `platformio.ini` and an FS image is uploaded.
-- CPU usage values remain zero until the main loop runs and CPU measurement is started.

-## Streaming API (WebSocket)
-
-### Overview
-
-The streaming API exposes an event-driven WebSocket at `/ws`. It bridges between external clients and the internal event bus:
-
-- Incoming WebSocket JSON `{ event, payload }` → `ctx.fire(event, payload)`
-- Local events → broadcasted to all connected WebSocket clients as `{ event, payload }`
-
-This allows real-time control and observation of the system without polling.
-
-### URL
-
-- `ws://<device-ip>/ws`
-
-### Message Format
-
-- Client → Device
-```json
-{
-  "event": "<event-name>",
-  "payload": "<json-string>" | { /* inline JSON */ }
-}
-```
-
-- Device → Client
-```json
-{
-  "event": "<event-name>",
-  "payload": "<json-string>"
-}
-```
-
-Notes:
-- The device accepts `payload` as a string or a JSON object/array. Objects are serialized into a string before dispatching to local subscribers to keep a consistent downstream contract.
-- A minimal ack `{ "ok": true }` is sent after a valid inbound message.
-
-#### Echo suppression (origin tagging)
-
-- To prevent the sender from receiving an immediate echo of its own message, the server injects a private field into JSON payloads:
-  - `_origin: "ws:<clientId>"`
-- When re-broadcasting local events to WebSocket clients, the server:
-  - Strips the `_origin` field from the outgoing payload
-  - Skips the originating `clientId` so only other clients receive the message
-  - If a payload is not valid JSON (plain string), no origin tag is injected and the message may be echoed
-
-### Event Bus Integration
-
-- The WebSocket registers an `onAny` subscriber to `NodeContext` so that all local events are mirrored to clients.
-- Services should subscribe to specific events via `ctx.on("<name>", ...)`.
-
-### Examples
-
-1) Set a solid color on NeoPattern:
-```json
-{
-  "event": "api/neopattern/color",
-  "payload": { "color": "#FF0000", "brightness": 128 }
-}
-```
-
-2) Broadcast a cluster event (delegated to core):
-```json
-{
-  "event": "cluster/broadcast",
-  "payload": {
-    "event": "api/neopattern/color",
-    "data": { "color": "#00FF00", "brightness": 128 }
-  }
-}
-```
-
-### Reference Implementation
-
-- WebSocket setup and bridging are implemented in `ApiServer`.
-- Global event subscription uses `NodeContext::onAny`.
-
-Related docs:
-- [`ClusterBroadcast.md`](./ClusterBroadcast.md) — centralized UDP broadcasting and CLUSTER_EVENT format
-
-### Things to consider
-
-- High-frequency updates can overwhelm ESP8266:
-  - Frequent JSON parse/serialize and `String` allocations fragment heap and may cause resets (e.g., Exception(3)).
-  - UDP broadcast on every message amplifies load; WiFi/UDP buffers can back up.
-  - Prefer ≥50–100 ms intervals; microbursts at 10 ms are risky.
-- Throttle and coalesce:
-  - Add a minimum interval in the core `cluster/broadcast` handler.
-  - Optionally drop redundant updates (e.g., same color as previous).
-- Reduce allocations:
-  - Reuse `StaticJsonDocument`/preallocated buffers in hot paths.
-  - Avoid re-serializing when possible; pass-through payload strings.
-  - Reserve `String` capacity when reuse is needed.
-- Yielding:
-  - Call `yield()` in long-running or bursty paths to avoid WDT.
-- Packet size:
-  - Keep payloads small to fit `ClusterProtocol::UDP_BUF_SIZE` and reduce airtime.

-# PixelStream Example
-
-This example demonstrates how to consume the `udp/raw` cluster event and drive a NeoPixel strip or matrix directly from streamed RGB data. Frames are provided as hex encoded byte triplets (`RRGGBB` per pixel).
-
-## Features
-
-- Subscribes to `udp/raw` via `NodeContext::on`.
-- Converts incoming frames into pixel colors for strips or matrices.
-- Supports serpentine (zig-zag) matrix wiring.
-
-## Payload Format
-
-Each packet is expected to be `RAW:` followed by `pixelCount * 3 * 2` hexadecimal characters. For example, for 8 pixels:
-
-```
-RAW:FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000
-```
-
-## Usage
-
-### Strip Mode
-
-Upload the example with `PIXEL_MATRIX_WIDTH` set to 0 (default). Send frames containing `PIXEL_COUNT * 3` bytes as hex.
-
-### Matrix Mode
-
-Set `PIXEL_MATRIX_WIDTH` to the number of columns. The controller remaps even/odd rows to support serpentine wiring.
-
-## Configuration
-
-Adjust `PIXEL_PIN`, `PIXEL_COUNT`, `PIXEL_BRIGHTNESS`, `PIXEL_MATRIX_WIDTH`, `PIXEL_MATRIX_SERPENTINE`, and `PIXEL_TYPE` through build defines or editing `main.cpp`.

-# Test Scripts
 
-This directory contains JavaScript test scripts to interact with the Spore device, primarily for testing cluster event broadcasting.
+This directory is intended for PlatformIO Test Runner and project tests.
 
-## Prerequisites
+Unit Testing is a software testing method by which individual units of
-
+source code, sets of one or more MCU program modules together with associated
-These scripts require [Node.js](https://nodejs.org/) to be installed on your system.
+control data, usage procedures, and operating procedures, are tested to
-
+determine whether they are fit for use. Unit testing finds problems early
-## How to Run
+in the development cycle.
-
-### 1. HTTP Cluster Broadcast Color (`test/http-cluster-broadcast-color.js`)
-
-This script sends HTTP POST requests to the `/api/cluster/event` endpoint on your Spore device. It broadcasts NeoPattern color changes across the cluster every 5 seconds.
-
-**Usage:**
-```
-node test/http-cluster-broadcast-color.js <device-ip>
-```
-Example:
-```
-node test/http-cluster-broadcast-color.js 10.0.1.53
-```
-This will broadcast `{ event: "api/neopattern/color", data: { color: "#RRGGBB", brightness: 128 } }` every 5 seconds to the cluster via `/api/cluster/event`.
-
-### 2. WS Local Color Setter (`test/ws-color-client.js`)
-
-Connects to the device WebSocket (`/ws`) and sets a solid color locally (non-broadcast) every 5 seconds by firing `api/neopattern/color`.
-
-**Usage:**
-```
-node test/ws-color-client.js ws://<device-ip>/ws
-```
-Example:
-```
-node test/ws-color-client.js ws://10.0.1.53/ws
-```
-
-### 3. WS Cluster Broadcast Color (`test/ws-cluster-broadcast-color.js`)
-
-Connects to the device WebSocket (`/ws`) and broadcasts a color change to all peers every 5 seconds by firing `cluster/broadcast` with the proper envelope.
-
-**Usage:**
-```
-node test/ws-cluster-broadcast-color.js ws://<device-ip>/ws
-```
-Example:
-```
-node test/ws-cluster-broadcast-color.js ws://10.0.1.53/ws
-```
-
-### 4. WS Cluster Broadcast Rainbow (`test/ws-cluster-broadcast-rainbow.js`)
-
-Broadcasts a smooth rainbow color transition over WebSocket using `cluster/broadcast` and the `api/neopattern/color` event. Update rate defaults to `UPDATE_RATE` in the script (e.g., 100 ms).
-
-**Usage:**
-```
-node test/ws-cluster-broadcast-rainbow.js ws://<device-ip>/ws
-```
-Example:
-```
-node test/ws-cluster-broadcast-rainbow.js ws://10.0.1.53/ws
-```
-Note: Very fast update intervals (e.g., 10 ms) may saturate links or the device.
