* feat: Add WebP format support for team member images

Phase 2: Quality & Format Improvements

Added:
- 27 WebP images for all team members (includes extras: team, lojban, tim, zuri)
- 1 AVIF image for brenda-alesi (new team member)
- Python automation script update-team-images.py for batch format updates
- Internal documentation: image-optimization-workflow.md

Updated:
- 9 team member markdown files with <picture> tags for multi-format support
- brenda-alesi.jpg (optimized new team member image)

Benefits:
- WebP provides ~30% better compression than JPEG
- Maintains visual quality with smaller file sizes
- Falls back gracefully: AVIF → WebP → JPG
- Improves page load performance

* feat: complete image optimization and mkdocs.sh v2 enhancements

Phase 1: WebP Image Generation (ALL team members)
- Generated WebP images for all 24 team members
- Updated 18 team profile markdown files with <picture> tags
- Progressive enhancement: AVIF → WebP → JPG fallback
- 95%+ browser support for optimized formats
- 30-60% bandwidth savings vs JPG-only

Phase 2: mkdocs.sh Script v2 (Major Enhancement)
- Added comprehensive command-line argument support
- Implemented pre-flight checks (Docker, image availability)
- Added color-coded logging (green/yellow/red)
- Added health check functionality
- Support for multiple commands: serve, build, clean, status, help
- Verbose logging mode (--verbose flag)
- Graceful container cleanup and shutdown
- AI-friendly error output with clear diagnostics
- Exit codes for automation
- Backward compatibility maintained

Phase 3: Documentation
- Created docs/internal/mkdocs-sh-v2-improvements.md
- Updated README.md with new mkdocs.sh usage section

Key Improvements:
