The Docker image's mcp-server process crashes on boot with
ERR_PNPM_WORKSPACE_PKG_NOT_FOUND (#314). supervisord starts it via
`pnpm start`, and pnpm 10 runs a dependency-sync check before the script.
From the isolated /app/mcp-server dir it tries to resolve
`@prompt-optimizer/core@workspace:*`, can't find the workspace sibling,
and aborts before node ever runs.
The built artifact is self-contained (deps bundled, NODE_PATH=/app), so the
pnpm wrapper is unnecessary. Call node directly, matching the `start` script:
node -r ./preload-env.cjs dist/start.cjs --transport=http --port=3000
Verified: mcp-server reaches RUNNING state and serves /mcp on a fresh build
from develop.
Fixes#314
