(workflow): add XeLaTeX, multi-document, and font support for presentations

- Add XeLaTeX compilation support for presentation/poster projects
- Add output directory support (-outdir=build) for compiled files
- Add font installation step for CI (custom fonts in fonts/ dir)
- Add multi-document compilation (additional documents like posters)
- Add get_documents_config() for multi-document project configuration
- Add get_workflow_config() for workflow-specific settings
- Update pyproject.toml template with [documents] and [workflow] sections
- Update artifact and release files to include all compiled PDFs

Closes #3
