Update GitHub Actions workflow templates for presentations

[prudhomm]

Summary

Extend the generated GitHub Actions workflow to support Beamer presentations with XeLaTeX compilation and multiple document outputs.

Motivation

The current workflow template in repository_setup.py is article-focused with pdflatex compilation. Presentation projects need:

• XeLaTeX compilation for custom fonts
• Output directory support (build/)
• Multiple document compilation (presentation + poster)
• Font setup in CI environment

Requirements

Workflow Updates

• Add XeLaTeX compilation path in workflow template
• Support build/ output directory
• Add font installation step when fonts are configured
• Support compiling multiple documents (configurable list)
• Update artifact paths for output directory

Configuration-Driven Workflow

• Read project type from pyproject.toml to determine compilation settings
• Support documents list in config for multi-document projects:

  [tool.article-cli]
  project_type = "presentation"
  
  [tool.article-cli.documents]
  main = "presentation.tex"
  additional = ["poster.tex"]

Example Workflow Changes

- name: Compile LaTeX document
  run: |
    latexmk -shell-escape -xelatex -outdir=build presentation.tex
    
- name: Compile Poster (if configured)
  run: |
    latexmk -shell-escape -xelatex -outdir=build poster.tex

Release Artifact Updates

• Include all compiled PDFs in release
• Support configurable artifact inclusion patterns

✅ Completed in PR #8

All requirements from this issue have been implemented:

Workflow Updates

• ✅ XeLaTeX compilation path: latexmk_use_xelatex: true for presentations/posters, -xelatex flag for self-hosted runners
• ✅ build/ output directory: output_dir parameter with -outdir=build args
• ✅ Font installation step: Font copying to ~/.local/share/fonts/ and fc-cache in CI
• ✅ Multiple document compilation: additional_documents list with separate compile steps
• ✅ Artifact paths updated for output directory

Configuration-Driven Workflow

• ✅ get_project_config() reads project type from pyproject.toml
• ✅ get_documents_config() supports main and additional documents list
• ✅ get_workflow_config() supports output_dir, fonts_dir, install_fonts

Example pyproject.toml config now supported:

[tool.article-cli.project]
type = "presentation"

[tool.article-cli.documents]
main = "presentation.tex"
additional = ["poster.tex"]

[tool.article-cli.workflow]
output_dir = "build"
fonts_dir = "fonts"
install_fonts = true
