🔧 Fix workflow linting errors:

- Remove validate_workflow.py from flake8 checks
- Add proper exit codes for linting steps
- Add .flake8 configuration file with standard rules
- Add proper exclusions for build artifacts
- Add per-file rule exceptions
- Add helpful documentation comments

These changes should fix the workflow failures
by removing references to deleted files and
providing proper linting configuration.
