* feat(service): expose MCP through HTTP backend
Serve JSON/SSE job endpoints and streamable HTTP MCP from one FastAPI application, sharing the same jobs and application lifecycle. Preserve the standalone MCP backend, add configurable MCP HTTP settings, update startup metadata and integration docs, and cover routing, lifecycle, configuration, and compatibility behavior with unit tests.
* fix(service): preserve MCP request protections
Route the exact MCP path through the complete FastMCP ASGI application so its middleware and state remain active. Reject non-literal MCP paths and validate reserved Job conflicts before tolerant service registration. Add regression coverage for middleware preservation, route syntax, and startup failure.
* fix(service): reject encoded MCP paths
Reject percent signs in mcp_path so ASGI path decoding cannot turn an accepted configuration into an unreachable route. Cover encoded slash, space, and double-encoded slash inputs.
* fix: show resolved service address in startup banner
* perf(website): reduce social preview image size
* fix: resolve MCP transport in startup banner
