CRITICAL FIXES:
- Fix build-initramfs.sh early exit preventing zinit installation
- Add binary detection/installation logic to setup-initramfs.sh
- Ensure compiled components are properly installed to initramfs
DOCUMENTATION:
- Update README.md to reflect actual implementation
- Document source compilation approach with git submodules
- Add development workflow and caching documentation
- Remove outdated GitHub releases references
This fixes the 'zinit not found' boot error by ensuring the build
pipeline completes all phases including initramfs assembly.
