feat(file-selection): add custom exclude patterns for file filtering

- Add exclude_patterns parameter to get_project_files endpoint for custom file filtering
- Support JSON-formatted exclude patterns array in API requests
- Integrate custom exclude patterns into ZIP and repository file scanning workflows
- Update should_exclude and is_text_file functions to support user-defined patterns
- Pass exclude_patterns through scan configuration in both scan_zip and scan_stored_zip endpoints
- Add ScanRequest model field for exclude_patterns to support pattern specification
- Implement file filtering logic that respects both default and custom exclusion rules
- Add comprehensive unit and E2E tests for file selection and exclusion pattern functionality
- Enable users to customize which files are scanned by specifying glob patterns like ["node_modules/**", "*.log"]
