Safi 2a683aac2e feat(serve): add Streamable HTTP transport to MCP server (#1143)
python -m graphify.serve graph.json --transport http --port 8080 serves
the same MCP tools over the Streamable HTTP transport (spec 2025-03-26)
so a single shared process can serve the graph for a whole team.

- _build_server() refactors server registration into a shared factory
  (stdio behavior is byte-for-byte unchanged — all 52 existing tests pass)
- _ApiKeyMiddleware: raw ASGI (not BaseHTTPMiddleware) preserves SSE
  streaming; constant-time compare; RFC-6750 case-insensitive Bearer;
  blank-key normalized to no-auth
- DNS-rebinding protection via TransportSecuritySettings; wildcard binds
  disable it and print an exposure warning when no api-key is set
- session_idle_timeout reaps idle stateful sessions (default 3600s) so a
  long-running shared server does not leak memory on client disconnect
- Dockerfile + .dockerignore for containerized team deployment
- 16 new tests via in-process ASGI test client (importorskip-guarded)
- stdio remains the default; no change for existing setups
