Implements federated command messages following TDD principles and
mirroring the QueryService pattern for consistency.
## Implementation
### Schema Changes
- Added commandType and payload fields to FederationMessage model
- Supports COMMAND message type (already defined in enum)
- Applied schema changes with prisma db push
### Type Definitions
- CommandMessage: Request structure with commandType and payload
- CommandResponse: Response structure with correlation
- CommandMessageDetails: Full message details for API responses
### CommandService
- sendCommand(): Send command to remote instance with signature
- handleIncomingCommand(): Process incoming commands with verification
- processCommandResponse(): Handle command responses
- getCommandMessages(): List commands for workspace
- getCommandMessage(): Get single command details
- Full signature verification and timestamp validation
- Error handling and status tracking
### CommandController
- POST /api/v1/federation/command - Send command (authenticated)
- POST /api/v1/federation/incoming/command - Handle incoming (public)
- GET /api/v1/federation/commands - List commands (authenticated)
- GET /api/v1/federation/commands/:id - Get command (authenticated)
## Testing
- CommandService: 15 tests, 90.21% coverage
- CommandController: 8 tests, 100% coverage
- All 23 tests passing
- Exceeds 85% coverage requirement
- Total 47 tests passing (includes command tests)
## Security
- RSA signature verification for all incoming commands
- Timestamp validation to prevent replay attacks
- Connection status validation
- Authorization checks on command types
## Quality Checks
- TypeScript compilation: PASSED
- All tests: 47 PASSED
- Code coverage: >85% (90.21% for CommandService, 100% for CommandController)
- Linting: PASSED
Fixes#89

Implements FED-004: Cross-Instance Identity Linking, building on the
foundation from FED-001, FED-002, and FED-003.
New Services:
- IdentityLinkingService: Handles identity verification and mapping
with signature validation and OIDC token verification
- IdentityResolutionService: Resolves identities between local and
remote instances with support for bulk operations
New API Endpoints (IdentityLinkingController):
- POST /api/v1/federation/identity/verify - Verify remote identity
- POST /api/v1/federation/identity/resolve - Resolve remote to local user
- POST /api/v1/federation/identity/bulk-resolve - Bulk resolution
- GET /api/v1/federation/identity/me - Get current user's identities
- POST /api/v1/federation/identity/link - Create identity mapping
- PATCH /api/v1/federation/identity/:id - Update mapping
- DELETE /api/v1/federation/identity/:id - Revoke mapping
- GET /api/v1/federation/identity/:id/validate - Validate mapping
Security Features:
- Signature verification using remote instance public keys
- OIDC token validation before creating mappings
- Timestamp validation to prevent replay attacks
- Workspace isolation via authentication guards
- Comprehensive audit logging for all identity operations
Enhancements:
- Added SignatureService.verifyMessage() for remote signature verification
- Added FederationService.getConnectionByRemoteInstanceId()
- Extended FederationAuditService with identity logging methods
- Created comprehensive DTOs with class-validator decorators
Testing:
- 38 new tests (19 service + 7 resolution + 12 controller)
- All 132 federation tests passing
- TypeScript compilation passing with no errors
- High test coverage achieved (>85% requirement exceeded)
Technical Details:
- Leverages existing FederatedIdentity model from FED-003
- Uses RSA SHA-256 signatures for cryptographic verification
- Supports one identity mapping per remote instance per user
- Resolution service optimized for read-heavy operations
- Built following TDD principles (Red-Green-Refactor)
Closes#87

Implements federated authentication infrastructure using OIDC:
- Add FederatedIdentity model to Prisma schema for identity mapping
- Create OIDCService with identity linking and token validation
- Add FederationAuthController with 5 endpoints:
* POST /auth/initiate - Start federated auth flow
* POST /auth/link - Link identity to remote instance
* GET /auth/identities - List user's federated identities
* DELETE /auth/identities/:id - Revoke identity
* POST /auth/validate - Validate federated token
- Create comprehensive type definitions for OIDC flows
- Add audit logging for security events
- Write 24 passing tests (14 service + 10 controller)
- Achieve 79% coverage for OIDCService, 100% for controller
Notes:
- Token validation and auth URL generation are placeholder implementations
- Full JWT validation will be added when federation OIDC is actively used
- Identity mappings enforce workspace isolation
- All endpoints require authentication except /validate

Implemented connection handshake protocol for federation building on
the Instance Identity Model from issue #84.
**Services:**
- SignatureService: Message signing/verification with RSA-SHA256
- ConnectionService: Federation connection management
**API Endpoints:**
- POST /api/v1/federation/connections/initiate
- POST /api/v1/federation/connections/:id/accept
- POST /api/v1/federation/connections/:id/reject
- POST /api/v1/federation/connections/:id/disconnect
- GET /api/v1/federation/connections
- GET /api/v1/federation/connections/:id
- POST /api/v1/federation/incoming/connect
**Tests:** 70 tests pass (18 Signature + 20 Connection + 13 Controller + 19 existing)
**Coverage:** 100% on new code
**TDD Approach:** Tests written before implementation
