* fix: Address Gemini Code Assist review issues in run-server.sh

- Fix hardcoded Unix paths (lines 563 & 568) with cross-platform detection
- Improve error handling by capturing uv stderr instead of /dev/null
- Fix uv environment detection logic to check uv_created marker file

Resolves three issues identified in PR review:
1. High Priority: Replace hardcoded $VENV_PATH/bin/python with detection
2. Medium Priority: Capture and display uv command errors for debugging
3. Medium Priority: Use marker file instead of path matching for uv detection
