<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Adds --workers to HTTP mode with validation, refactors server
startup/discovery for multi-process uvicorn, and removes all
Docker-related files/configs.
>
> - **MCP Server (HTTP mode)**
> - Add `--workers` arg to run multiple uvicorn workers; block `workers
> 1` with `stdio`, and `reload` with multiple workers.
> - Refactor startup: move tool discovery/config into
`create_arcade_mcp_factory()` driven by env vars; use `uvicorn.run(...,
workers=...)` for multi-worker/reload; retain `serve_with_force_quit()`
only for single-worker.
> - Adjust CLI to only discover tools in `stdio` path; HTTP path now
delegates discovery to the factory.
> - **MCPApp**
> - Minor run path cleanup; continue using `serve_with_force_quit()` for
single-worker HTTP.
> - **Ops/Packaging**
> - Remove `docker/` directory and all Dockerfiles, compose/configs, and
docs.
