feat(docker): add /healthz endpoint and -healthcheck flag (#254)

Adds a Docker healthcheck and the small HTTP/CLI plumbing it needs.

- Expose `GET /healthz` on the HTTP-mode server.
- Add `-healthcheck` to dial `http://127.0.0.1:<port>/healthz` and exit with status.
- Add a Dockerfile `HEALTHCHECK` instruction using `-healthcheck`.
- Document HTTP-mode usage and stdio override guidance.

HTTP is always stateless: `/mcp` accepts POST only, without `Mcp-Session-Id`, standalone SSE or `Last-Event-ID` resumability. Origins are validated, and reverse proxies must forward `Mcp-Protocol-Version`, `Mcp-Method` and `Mcp-Name` unchanged. `Authorization: Bearer <token>` and `Authorization: token <token>` pass a Gitea credential per request, which is credential passthrough rather than MCP OAuth.
HTTP mode also serves `/healthz`, which returns `200 OK` when the server is up. The Docker image's built-in `HEALTHCHECK` runs `gitea-mcp -healthcheck`, which dials `http://127.0.0.1:<port>/healthz` using the same `-p`/`-port` value (or `8080` by default) and exits `0` on success or `1` on failure. Stdio deployments do not serve `/healthz`, so override or disable the image's `HEALTHCHECK` when running in stdio mode.
