Initial commit: Piglet - Animated figlet wrapper

Add complete Rust implementation with:
- 20+ motion effects (fade, slide, scale, typewriter, wave, bounce, etc.)
- 18+ easing functions (linear, quad, cubic, elastic, back, bounce)
- Color support (CSS4 colors, hex codes, gradients)
- Figlet integration with custom fonts and options
- Cross-platform support (Linux, macOS, Windows)
- Comprehensive CI/CD workflows
- Full test suite with integration tests
- Documentation (README.md, CLAUDE.md)
