- Remove component copying from build functions (build_zinit, build_rfs, etc)
- Add initramfs_copy_components() function to copy built components to initramfs
- Add components_copy stage between init_script and modules_setup
- Fix components_verify to check built components (not initramfs locations)
- Now supports partial builds: build components separately, copy later
- All 4 components (zinit 8.1M, rfs 13M, mycelium 21M, corex 4.0M) working
