[WIP] Add PDF generation for ipynb files

[Copilot]

Summary

Successfully implemented a GitHub Actions workflow that automatically generates PDFs from all Jupyter notebooks when a new release is created or published.

Completed Tasks

• Create .github/workflows directory
• Create GitHub Actions workflow for PDF generation on release draft
• Configure workflow to install dependencies (nbconvert, jupyter, pandoc, texlive)
• Convert all .ipynb files to PDFs
• Upload PDFs as release assets
• Update .gitignore to exclude PDF files from repository
• Make workflow resilient to handle conversion errors gracefully
• Test PDF conversion locally (13 of 14 notebooks convert successfully)
• Pin package versions for reproducible builds
• Add safety checks for glob expansion
• Address all code review feedback
• Add explicit permissions to workflow
• Pass security scan with 0 alerts

Key Features

1. Automated PDF Generation: Workflow triggers on release creation/publishing events
2. Complete Dependency Installation: Installs pandoc, texlive, jupyter, and nbconvert
3. Error Resilience: Continues processing even if individual notebook conversions fail
4. Security Compliant: Explicit permissions set, passes CodeQL security scan
5. Reproducible Builds: Pinned package versions (jupyter==1.1.1, nbconvert==7.16.6)
6. Safe Glob Handling: Proper checks to prevent issues with empty file sets
7. Clean Repository: No PDF files or generation scripts committed to the repository

Testing

• Tested PDF conversion locally: 13 out of 14 notebooks convert successfully
• One notebook (10_testunit.ipynb) has a pandoc parsing issue, but the workflow handles it gracefully
• YAML syntax validated
• Security scan passed with 0 alerts

Files Changed

• .github/workflows/generate-pdfs-on-release.yml (new): GitHub Actions workflow
• .gitignore (modified): Added exclusions for PDF files and pdfs/ directory
