fix: resolve Docker validation race conditions and sudo prefix bug

- Fix sudo prefix bug: Use word boundary matching to prevent 'do' keyword from matching 'docker' commands
- Add ensureProxyNetworksExist() helper to create networks before docker compose up
- Ensure networks exist synchronously before dispatching async proxy startup to prevent race conditions
- Update comprehensive unit tests for sudo parsing (50 tests passing)

This resolves issues where Docker commands failed to execute with sudo on non-root servers and where proxy networks were not created before the proxy container started.
