Jukka Aho 1636e255fe docs: Add YAML front matter to all documentation files
**Purpose:** Prepare documentation for publishing as blog posts or book

**YAML Headers Include:**
- title: Document title
- subtitle: Optional subtitle for context
- description: Brief summary for SEO/indexing
- date: Creation date
- updated: Last update date (for status docs)
- author: Jukka Aho
- categories: Taxonomic classification
- keywords: Search/indexing keywords
- audience: Target reader (users/contributors/researchers)
- level: Difficulty level (beginner/intermediate/advanced/expert)
- type: Document type (manual/guide/theory/benchmark/status)
- series: Which manual it belongs to
- chapter: Book structure (for The JuliaFEM Book)
- status: Current state (completed/work in progress/active maintenance)
- math: Whether document contains mathematical notation
- prerequisites: Required background knowledge
- tools: Software/packages used (for benchmarks)
- context: Background information

**Files Updated:**
- docs/README.md (main index)
- docs/user/README.md (user manual index)
- docs/contributor/README.md (contributor manual index)
- docs/book/README.md (book index)
- docs/contributor/testing_philosophy.md
- docs/contributor/status.md
- docs/contributor/test_fixes_needed.md
- docs/book/lagrange_basis_functions.md
- docs/book/benchmarks/shape_function_derivatives_ad_vs_manual.md
- scripts/README.md

**Benefits:**
- Ready for static site generators (Jekyll, Hugo, MkDocs)
- Can generate book with proper metadata
- SEO-friendly with descriptions and keywords
- Clear audience/level targeting
- Trackable with dates and status
- Organized by series and chapters

**Compatible With:**
- Jekyll (GitHub Pages)
- Hugo (fast static site generator)
- MkDocs (Python-based documentation)
- Jupyter Book (interactive books)
- Docusaurus (React-based docs)
- Custom publishing scripts

JuliaFEM Contributor Manual

Audience: Developers, contributors, advanced users who want to extend or modify JuliaFEM.

This manual is technical and detailed - it explains HOW the code works and WHY we made certain design choices.

What's Here

  • Testing Philosophy: How and why we test
  • Code Style: Conventions and best practices
  • Architecture: Module structure, data flow, key abstractions
  • Performance: Zero-allocation design, profiling, benchmarking
  • Adding Elements: How to implement new element types
  • CI/CD: Continuous integration, releases, versioning
  • Git Workflow: Branching, commits, pull requests

What's NOT Here

  • User tutorials (see docs/user/ for that)
  • Deep mathematical theory (see docs/book/ for that)
  • "How do I solve problem X?" (that's user docs)

Philosophy

"Show me the code AND tell me why."

We assume you:

  • Know Julia reasonably well
  • Understand FEM basics
  • Want to add features or fix bugs
  • Care about performance and correctness
  • Need to understand design rationale

Before Contributing

  1. Read Testing Philosophy
  2. Understand Architecture
  3. Follow Code Style
  4. Check Performance Guidelines
  5. Review Git Workflow

Key Principles

  • Type stability: No Any, no Dict without types
  • Zero allocations: Hot paths should allocate nothing
  • Immutability: Prefer struct over mutable struct
  • Composition: Use tuples and free functions, not OOP hierarchies
  • Explicit: No magic, user knows what happens
  • Test first: Write tests before fixing bugs
