Add utility scripts collection with auto-generated documentation

Browse Source 
This commit introduces a comprehensive collection of utility scripts for shell
automation, color manipulation, and documentation generation:

Core Scripts:
- artifact_github_download.sh: Download GitHub Action artifacts via CLI
- css_color_filter.sh: Generate CSS filter values using SPSA algorithm
- css_color_palette.sh: Generate comprehensive color palettes (monochromatic, triadic, etc.)
- css_json_convert.sh: Convert CSS variables to JSON/YAML formats
- doc_bash_generate.sh: Auto-generate README.md with animated GIF demos
- doc_rust_generate.sh: Generate Rust project documentation
- jinja_template_render.sh: Render Jinja2 templates from CLI
- mime_mp4_gif.sh: Convert MP4 videos to GIF format

Documentation Features:
- Comprehensive README.md with table of contents
- 8 animated GIF demos showing real command examples
- Sandboxed demo execution in temporary directories
- 15-second timeout protection for intensive computations
- Automatic example extraction from --help output

Technical Implementation:
- Pure bash color utilities using only bc for arithmetic
- tput-based color codes for portability
- IFS-safe string parsing using parameter expansion
- Stdout/stderr isolation to prevent contamination
- Base64 encoding for multi-line text preservation

All scripts include detailed --help documentation with usage examples.
