Feat/streamable http transport (#6)

* docs: add Redis session store implementation plan

Ultraworked with Sisyphus (oh-my-opencode).

* feat: add Redis module and session repository

Add @global RedisModule with ioredis provider (retry strategy, graceful disconnect), Redis constants (REDIS_CLIENT token, key prefixes), and RedisSessionRepository for session CRUD with TTL and stale SET member pruning. Add RedisSessionData interface to session DTO.

* feat: integrate Redis session store into MCP module

Rewrite SessionManagerService to use Redis-backed metadata with local McpServer cache. Add await to async session calls in McpController. Wire RedisSessionRepository into McpModule. Import RedisModule in AppModule. Update .env.example with required Redis vars.

* docs: add deployment scripts and comprehensive codebase knowledge files

Add deploy.sh (unified VPS deploy with backup/rollback for prod+staging). Rewrite AGENT.md with full architecture, module map, data flow, and conventions. Create AGENTS.md (hierarchical subagent knowledge). Create docs/DEPLOYMENT.md (ops runbook). Move redis-plan.md to docs/feature-plan/.

* refactor: update auth passthrough to use SDK authInfo pattern

Update tool-registry to extract Bearer token from extra.authInfo instead of extra.sessionId. Add optional existingSessionId parameter to session-manager for SDK-managed session IDs.

* feat: replace custom JSON-RPC handler with SDK StreamableHTTPServerTransport

Replace hand-rolled JSON-RPC dispatch with official @modelcontextprotocol/sdk StreamableHTTPServerTransport. Adds POST/GET/DELETE handlers for full MCP Streamable HTTP spec compliance, enabling n8n and other SDK-compliant clients to connect. Remove McpProtocolHandlerService from module (superseded by SDK transport).

* fix: update CORS headers for MCP Streamable HTTP and staging port

Add DELETE to CORS methods, mcp-session-id to allowed/exposed headers for SDK transport. Fix staging docker-compose PORT default from 3001 to 3002 to match host mapping.
