docs: Align documentation with true microservices architecture

Transform all documentation from modular monolith to true microservices
architecture where core services are independently deployable.

Key Changes:
- Core Kernel: Infrastructure only (no business logic)
- Core Services: Auth, Identity, Authz, Audit as separate microservices
  - Each service has own entry point (cmd/{service}/)
  - Each service has own gRPC server and database schema
  - Services register with Consul for service discovery
- API Gateway: Moved from Epic 8 to Epic 1 as core infrastructure
  - Single entry point for all external traffic
  - Handles routing, JWT validation, rate limiting, CORS
- Service Discovery: Consul as primary mechanism (ADR-0033)
- Database Pattern: Per-service connections with schema isolation

Documentation Updates:
- Updated all 9 architecture documents
- Updated 4 ADRs and created 2 new ADRs (API Gateway, Service Discovery)
- Rewrote Epic 1: Core Kernel & Infrastructure (infrastructure only)
- Rewrote Epic 2: Core Services (Auth, Identity, Authz, Audit as services)
- Updated Epic 3-8 stories for service architecture
- Updated plan.md, playbook.md, requirements.md, index.md
- Updated all epic READMEs and story files

New ADRs:
- ADR-0032: API Gateway Strategy
- ADR-0033: Service Discovery Implementation (Consul)

New Stories:
- Epic 1.7: Service Client Interfaces
- Epic 1.8: API Gateway Implementation

+- **Title**: Service Management CLI Tool
+- **Epic**: 3 - Module Framework (Feature Services)
 - **Status**: Pending
 - **Priority**: Medium
 - **Estimated Time**: 4-5 hours

 ## Goal
-Provide CLI tooling for managing modules, validating dependencies, and testing module loading.
+Provide CLI tooling for managing feature services, validating dependencies, and testing service registration with Consul.
 
 ## Description
-This story creates a CLI tool that allows developers and operators to manage modules, validate dependencies, test module loading, and inspect module information.
+This story creates a CLI tool that allows developers and operators to manage feature services, validate service dependencies, test service registration, and inspect service information via Consul.
 
 ## Deliverables
 
 ### 1. CLI Tool (`cmd/platformctl/main.go`)
-- `platformctl modules list` - List all loaded modules with versions
-- `platformctl modules validate` - Validate module dependencies
-- `platformctl modules test <module>` - Test module loading
-- `platformctl modules info <module>` - Show module details
-- `platformctl modules dependencies <module>` - Show module dependencies
+- `platformctl services list` - List all services registered in Consul
+- `platformctl services validate` - Validate service dependencies
+- `platformctl services test <service>` - Test service registration and health
+- `platformctl services info <service>` - Show service details from Consul
+- `platformctl services dependencies <service>` - Show service dependencies
+- `platformctl services health <service>` - Check service health
 - Command-line argument parsing
 - Error handling and user-friendly output
