- Add configurable shell integration timeout in VS Code settings (roo-cline.terminalShellIntegrationTimeout)
- Add automatic Theia IDE detection for better error messages
- Add debug logging for shell integration signal detection
- Create comprehensive Theia compatibility documentation
- Default timeout remains 5 seconds, configurable from 1-30 seconds
This addresses issue #9102 where Theia IDE users experienced shell integration
initialization failures due to insufficient timeout and lack of configuration options.
