Add internal/metrics package with Prometheus collectors (HTTP requests,
duration, messages, agents, connections) and chi-compatible middleware.
Add internal/health package with /healthz (liveness) and /readyz
(readiness with DB ping) endpoints. Wire into main.go with promhttp
handler at /metrics.

Add HNSW-based vector search with configurable embedding providers
(OpenAI, Ollama) and automatic FTS5 fallback when no provider is
configured. Background pipeline embeds messages asynchronously on
ingest, stores vectors in a pure-Go HNSW index, and retries on
failure with exponential backoff. The search_messages MCP tool now
supports search_mode (auto/semantic/fulltext) and returns ranked
results with similarity scores. All existing tests continue to pass,
CGO_ENABLED=0 cross-compilation verified.

Add complete auth subsystem with OAuth 2.1 authorization server using
ory/fosite, local user accounts with bcrypt password hashing, session
management, and HTTP handlers for the Web UI.
Components:
- User store with bcrypt hashing (configurable cost, default 12), CRUD,
validation (username 3-64 chars alphanumeric+underscore, password 8-72 bytes)
- Session store with secure random IDs, configurable lifetime (default 24h),
expiration cleanup, and per-user invalidation
- OAuth client store with client_id/secret generation and bcrypt verification
- Fosite storage adapter implementing CoreStorage, TokenRevocationStorage,
and PKCERequestStorage backed by SQLite
- OAuth provider configured with authorization code (PKCE S256 mandatory),
client credentials, refresh token rotation, and token introspection
- HTTP handlers: POST /auth/register, POST /auth/login, POST /auth/logout,
GET /auth/me, PUT /auth/password, GET /oauth/authorize, POST /oauth/token,
POST /oauth/introspect
- Middleware: RequireSession (cookie), RequireBearer (access token),
RequireAuth (either), RequireAdmin (role check)
- Structured auth event logging (login, token issuance, session lifecycle)
- Schema migration 002_auth.sql extending users, oauth_clients, oauth_tokens
tables and adding sessions, oauth_authorization_codes tables
- Initial admin user auto-created on first run with random password printed
to stdout
- All tests pass with CGO_ENABLED=0, zero external runtime dependencies

Implements the foundational layer that all SynapBus features depend on:
- internal/storage: SQLite connection manager (WAL mode, busy_timeout,
foreign_keys) and embedded migration runner using modernc.org/sqlite
- internal/messaging: MessagingService with send, read inbox, claim,
mark done/failed, and FTS5 search. SQLite-backed MessageStore with
conversation auto-creation and read/unread tracking via inbox_state.
- internal/agents: AgentService with register, authenticate (bcrypt),
update, deregister, discover by capability. HTTP auth middleware.
- internal/mcp: MCP server using mark3labs/mcp-go with 9 registered
tools (send_message, read_inbox, claim_messages, mark_done,
search_messages, register_agent, discover_agents, update_agent,
deregister_agent). SSE transport, health endpoint, connection manager.
- internal/trace: Async trace recorder with buffered channel for
recording agent actions to SQLite traces table.
- cmd/synapbus: Updated main.go wiring storage, migrations, services,
MCP server, chi router, and graceful shutdown.
All code compiles with CGO_ENABLED=0. Full test suite passes.
