Performance improvements: fix MCP server shutdown and disable caching

Browse Source 
- Add proper shutdown handling for MCP servers
  - Listen for stdin EOF (main issue causing 6min delays)
  - Add transport.close() to properly close connections
  - Add 5-minute timeout safety net
  - Handle SIGHUP signal
- Disable Bun caching to avoid timeout errors
- Add Dockerfile.runner for pre-built container option
- Create optimized workflow example without container layer
