Subject: [PATCH] feat: Add Linux build support

- Conditionally compile install module for Windows/macOS only
- Show helpful message on Linux when run without flags
- Add build-linux job to GitHub Actions workflow
- Include Linux binary in release artifacts
- Add --http-only flag for standalone HTTP server mode (no MCP stdio)
