teknium1 64ff8f065b feat(mcp): add HTTP transport, reconnection, security hardening
Upgrades the MCP client implementation from PR #291 with:

- HTTP/Streamable HTTP transport: support 'url' key in config for remote
  MCP servers (Notion, Slack, Sentry, Supabase, etc.)
- Automatic reconnection with exponential backoff (1s-60s, 5 retries)
  when a server connection drops unexpectedly
- Environment variable filtering: only pass safe vars (PATH, HOME, etc.)
  plus user-specified env to stdio subprocesses (prevents secret leaks)
- Credential stripping: sanitize error messages before returning to the
  LLM (strips GitHub PATs, OpenAI keys, Bearer tokens, etc.)
- Configurable per-server timeouts: 'timeout' and 'connect_timeout' keys
- Fix shutdown race condition in servers_snapshot variable scoping

Test coverage: 50 tests (up from 30), including new tests for env
filtering, credential sanitization, HTTP config detection, reconnection
logic, and configurable timeouts.

All 1162 tests pass (1162 passed, 3 skipped, 0 failed).
