Starlette's Mount("/mcp", ...) only matches /mcp/* paths. A POST to bare
/mcp falls through to the catch-all Django mount and returns 404. The
fast-agent MCP client and the README example both used the no-slash URL,
so the validator was never able to initialize a session — every call
landed in django.request.
Adds a 307 redirect at /mcp so any client URL works, and points the
validator config at /mcp/ directly to skip the redirect round-trip.
Also gitignores fastagent.jsonl (a runtime log file fast-agent writes
into the working directory).
