chore: final pre-submission polish for JOSS

- Add CITATION.cff for GitHub citation support and Zenodo/JOSS integration
- Fix ossim reference URL in references.bib (was pointing to unrelated repo)
- Remove broken favicon reference from index.html (no public/ directory exists)
- Add meta description to index.html
- Fix sidebar title inconsistency: "Process Simulator" → "Process Scheduler Simulator"
- Rebuild dist.tar.gz with production assets
