Add project type support (article, presentation, poster)

[prudhomm]

Summary

Extend article-cli to support different LaTeX project types beyond articles, including Beamer presentations and posters.

Motivation

The tool is currently article-centric. Many academic workflows require presentations (Beamer) and posters alongside articles. Supporting these as first-class project types enables:

• Appropriate default templates per project type
• Correct compilation settings (e.g., XeLaTeX for presentations with custom fonts)
• Type-specific GitHub Actions workflows

Requirements

• Add project_type configuration option: article, presentation, poster
• Store project type in pyproject.toml under [tool.article-cli]
• Update init command with --type option
• Create template generation based on project type
• Add [tool.article-cli.presentation] config section for presentation-specific options:
  • theme: Beamer theme name (e.g., numpex, metropolis)
  • aspect_ratio: 169, 43, 1610
  • font_theme: Optional font theme
  • color_theme: Optional color theme
• Add [tool.article-cli.poster] config section for poster-specific options

Configuration Example

[tool.article-cli]
project_type = "presentation"

[tool.article-cli.presentation]
theme = "numpex"
aspect_ratio = "169"
