Replace deeply nested Either case expressions with clean ExceptT monad
transformer pipeline. This eliminates manual error propagation and
creates a more readable "straight line" flow while preserving identical
error handling semantics.

- Remove Text.Pandoc.PDF dependency and dummy Pandoc document
- Add direct xelatex invocation with temporary file handling
- Improve error reporting with LaTeX log file parsing
- Add temporary package dependency for proper temp file cleanup
- Maintain same external API while cleaning internal architecture
- Eliminate architectural mismatch between our pipeline and Pandoc's expectations
The previous code used makePDF in a way that fought against its intended usage,
requiring a dummy Pandoc document. Now we directly call xelatex after our
custom LaTeX template processing, creating a cleaner separation of concerns.

Replace manual size constraints with LaTeX's built-in image scaling mechanism.
- Remove artificial width/height constraints that caused diagram truncation
- Add adjustbox package and auto-scaling macros to LaTeX template
- Images now scale intelligently: natural size if they fit, auto-scaled if oversized
- Maintains aspect ratio and prevents page rotation issues

Problem: SVG diagrams had missing text in PDFs due to Inkscape conversion
issues with foreignObject elements used by Mermaid for HTML text rendering.
Solution: Implement format-specific optimal generation:
- HTML: SVG files for perfect vector scaling and text rendering
- PDF: High-resolution PNG files (3x scale) for sharp images with readable text
Changes:
- Generate SVG for HTML output using standard mmdc command
- Generate PNG for PDF output using mmdc with --scale 3 for high resolution
- Remove SVG LaTeX package dependency and Inkscape requirement
- Update documentation to reflect the dual-format approach
Results:
- HTML: Crisp, scalable vector diagrams with perfect text
- PDF: Sharp, high-resolution raster diagrams with clear text
- No external dependencies beyond mermaid-cli

Problem: HTML output contained broken image links because all formats
used the same full path (e.g., living-documentation/diagram-536389.png).
This worked for PDFs but failed for HTML since both files are in the
same directory and need relative paths.
Solution:
- Add output format detection with isHTMLOutput function
- Update processMermaidBlock to take OutputPath parameter
- Generate context-appropriate paths:
* HTML: relative path (diagram-536389.png)
* PDF: full path (living-documentation/diagram-536389.png)
- Update transformDocument and compilation functions to pass output path
Both HTML and PDF generation now work correctly with proper image embedding.

Major improvements:
- Add custom DocsterError type with proper exception handling
- Introduce type-safe newtypes (SourceDir, OutputPath, DiagramId)
- Consistent Text usage throughout, eliminating String/Text mixing
- Extract LaTeX template generation into separate functions
- Add resource cleanup with bracket pattern for temporary files
- Improve function naming and comprehensive documentation
- Extract constants for better maintainability
- Remove all unused imports and fix compiler warnings
The refactored code maintains identical functionality while being
much more maintainable, type-safe, and following Haskell best practices.
