Add workspace cleanup stage to Jenkins pipeline

- Added 'Clean Workspace' stage to remove all processed_*.lsl files before preprocessing
- Fixed documentation generation to only process original source files
- This will clean up the hundreds of recursive processed files from Jenkins workspace
- Pipeline now starts with a clean slate on each build
