feat(dx): add fastmcp.json configs, module-level tool registration, tool timeout

- Add fastmcp.http.json and fastmcp.stdio.json declarative server configs
  for streamable-http (:6970) and stdio transports respectively
- Move register_all_modules() to module level in server.py so
  `fastmcp run server.py --reload` discovers the fully-wired mcp object
  without going through run_server() — tools registered exactly once
- Add timeout=120 to @mcp.tool() decorator as a global safety net;
  any hung subaction returns a clean MCP error instead of hanging forever
- Document fastmcp run --reload, fastmcp list, fastmcp call in README
- Bump version 1.0.1 → 1.1.0
