fix(SEC-ORCH-2): Add API key authentication to orchestrator API
Some checks failed
ci/woodpecker/push/woodpecker Pipeline failed
Details
000145af96 
Add OrchestratorApiKeyGuard to protect agent management endpoints (spawn,
kill, kill-all, status) from unauthorized access. Uses X-API-Key header
with constant-time comparison to prevent timing attacks.

- Create apps/orchestrator/src/common/guards/api-key.guard.ts
- Add comprehensive tests for all guard scenarios
- Apply guard to AgentsController (controller-level protection)
- Document ORCHESTRATOR_API_KEY in .env.example files
- Health endpoints remain unauthenticated for monitoring

Security: Prevents unauthorized users from draining API credits or
killing all agents via unprotected endpoints.

fix(#337): Sanitize HTML before wiki-link processing in WikiLinkRenderer aa14b580b3 
- Apply DOMPurify to entire HTML input before parseWikiLinks()
- Prevents stored XSS via knowledge entry content (SEC-WEB-2)
- Allow safe formatting tags (p, strong, em, etc.) but strip scripts, iframes, event handlers
- Update tests to reflect new sanitization behavior

fix(#337): Return error state from secret scanner on scan failures 6bb9846cde 
- Add scanError field and scannedSuccessfully flag to SecretScanResult
- File read errors no longer falsely report as "clean"
- Callers can distinguish clean files from scan failures
- Update getScanSummary to track filesWithErrors count
- SecretsDetectedError now reports files that couldn't be scanned
- Add tests verifying error handling behavior for file access issues

fix(#337): Propagate database errors from guards instead of masking as access denied e237c40482 
SEC-API-2: WorkspaceGuard now propagates database errors as 500s instead of
returning "access denied". Only Prisma P2025 (record not found) is treated
as "user not a member".

SEC-API-3: PermissionGuard now propagates database errors as 500s instead of
returning null role (which caused permission denied). Only Prisma P2025 is
treated as "not a member".

This prevents connection timeouts, pool exhaustion, and other infrastructure
errors from being misreported to users as authorization failures.

fix(#337): Fix boolean logic bug in ReactFlowEditor (use || instead of ??) 3055bd2d85

  * readOnly=false with selection: editing enabled
  * readOnly=true: editing always disabled

fix(#338): Bind CSRF token to user session with HMAC 7390cac2cc 
- Token now includes HMAC binding to session ID
- Validates session binding on verification
- Adds CSRF_SECRET configuration requirement

preventing token reuse across sessions and mitigating session fixation
attacks.

Token format: {random_part}:{hmac(random_part + user_id, secret)}

fix(#338): Add circuit breaker to coordinator loops 1852fe2812 
Implement circuit breaker pattern to prevent infinite retry loops on
repeated failures (SEC-ORCH-7). The circuit breaker tracks consecutive
failures and opens after a threshold is reached, blocking further
requests until a cooldown period elapses.

Circuit breaker states:
- CLOSED: Normal operation, requests pass through
- OPEN: After N consecutive failures, all requests blocked
- HALF_OPEN: After cooldown, allow one test request

Changes:
- Add circuit_breaker.py with CircuitBreaker class
- Integrate circuit breaker into Coordinator.start() loop
- Integrate circuit breaker into OrchestrationLoop.start() loop
- Integrate per-agent circuit breakers into ContextMonitor
- Add comprehensive tests for circuit breaker behavior
- Log state transitions and circuit breaker stats on shutdown

Configuration (defaults):
- failure_threshold: 5 consecutive failures
- cooldown_seconds: 30 seconds

- Implement filterEnvVars() to separate allowed/filtered vars
- Log security warning when non-whitelisted vars are filtered

docs: Update compaction protocol - agents cannot invoke /compact
Some checks failed

Details

CRITICAL finding: Agents cannot trigger compaction
- "compact and continue" does NOT work
- Only user typing /compact in CLI works
- Auto-compact at ~95% is too late

Updated protocol:
- Stop at 55-60% context usage
- Output COMPACTION REQUIRED checkpoint
- Wait for user to run /compact and say "continue"
