Reduce App package sizes (#453)
## Summary
- Trim Electron app packaging to only include runtime shell assets and
remove unused workspace runtime dependencies.
- Copy server resources explicitly, filtering stale build artifacts and
pruning known non-runtime dependency files.
- Bundle only the Node executable instead of the full Node distribution.

## Validation
- Built macOS Electron artifacts with `npm run build:mac --workspace
@neuralnomads/codenomad-electron-app`.
- Ran packaged server CLI smoke test: `dist/bin.js --version` returned
`0.16.0`.
- Ran packaged dependency import smoke test for pruned runtime
dependencies.

## Size Impact
- macOS x64 zip: 161M
- macOS arm64 zip: 161M
- macOS arm64 app bundle: 435M
- Packaged server node_modules: 25M
