feat: add binary optimization with strip and upx compression
...
- Added upx package to Dockerfile.alpine build dependencies
- Added optimize_binary() function to compile-components.sh
- Automatically strips debug symbols from all Zero-OS binaries
- Applies UPX compression with --best --lzma for maximum size reduction
- Optimizes binaries in both initramfs and output directories
- Shows size reduction stats (original → stripped → compressed)
- Graceful fallback if UPX fails, keeping stripped version
This significantly reduces initramfs size by compressing zinit, rfs, and mycelium binaries.

feat: Create minimal Zero-OS initramfs with console support
...
- Fixed build system to clone source repositories instead of downloading binaries
- Enhanced scripts/fetch-github.sh with proper git repo cloning and branch handling
- Updated scripts/compile-components.sh for RFS compilation with build-binary feature
- Added minimal firmware installation for essential network drivers (73 modules)
- Created comprehensive zinit configuration set (15 config files including getty)
- Added util-linux package for getty/agetty console support
- Optimized package selection for minimal 27MB initramfs footprint
- Successfully builds bootable vmlinuz.efi with embedded initramfs
- Confirmed working: VM boot, console login, network drivers, zinit init system
Components:
- initramfs.cpio.xz: 27MB compressed minimal Zero-OS image
- vmlinuz.efi: 35MB bootable kernel with embedded initramfs
- Complete Zero-OS toolchain: zinit, rfs, mycelium compiled from source

Migrate to Rust workspace with git subtrees
...
MAJOR ARCHITECTURAL CHANGE:
- Add Rust components as git subtrees: zinit, mycelium, rfs
- Replace git submodules with unified Rust workspace
- Update compile-components.sh to use workspace build
- Remove obsolete setup-submodules.sh script
- Keep CoreX handling in fetch-github.sh (Go binary)
BENEFITS:
- Unified dependency management across Rust components
- Single 'cargo build --workspace' command
- Better IDE support and shared target directory
- Improved build caching and version consistency
Components structure:
- components/zinit (subtree from threefoldtech/zinit)
- components/mycelium (subtree from threefoldtech/mycelium)
- components/rfs (subtree from threefoldtech/rfs)
- CoreX handled by fetch-github.sh (binary download)

Add cleanup script and remove unused git version variables
...
- Add comprehensive cleanup script (scripts/cleanup.sh) to remove build artifacts
- Remove unused VERGEN_GIT_* environment variables from Rust build functions
- Cleanup script preserves source code while removing outputs, cache, and temp files
