## Summary

This update improves the Python deployment process, adds comprehensive
E2E and unit tests, and refines tool behavior based on real-world usage.

## Deployment Enhancements

### Python Dependency Installation
- Handle 'Dequeued' status correctly as an intermediate state
- Explicitly trigger CreateDependencyInstallTask before polling
- Increase timeout to 300 seconds for dependency installation
- Refactor release_function to reuse SDK wait_for_dependency_install logic

### Script Permissions
- Preserve original file permissions when packaging
- Proactively grant 755 to script files (.sh, .bash, .py, .pl, .rb)
- Fixes 'Permission denied' errors for run.sh

### Configuration Management
- Add vefaas.yaml to DEFAULT_VEFAASIGNORE
- Save config in update_function when project_path is provided
- Fix NAME_CONFLICT error messages to require user decision

## Tool Behavior Improvements

### update_function
- Refined next_step message to not auto-trigger release_function
- Gives user control over when to publish changes

### release_function
- Enhanced to correctly handle Dequeued status
- Reuses SDK dependency waiting logic for consistency

## Code Quality

### Cleanup
- Removed all debugging logger.debug statements
- Translated Chinese comments to English
- Fixed deprecated pathspec 'gitwildmatch' -> 'gitignore'

## Tests

### E2E Tests (tests/test_e2e.py)
- Application Workflow (Python/Node.js): Deploy + Update + Redeploy
- Function Local Dev (Python/Node.js): Deploy + Update Code + Release

### Unit Tests (tests/test_unit.py) - 18 tests
- Package directory and ignore patterns
- Caddyfile generation
- Project detection (FastAPI, Flask, Vite)
- Configuration read/write
- App name generation
