Add strip + UPX optimization during component copying

Browse Source 
- Add strip and UPX compression to initramfs_copy_components()
- Applied during component copying phase (not build phase)
- Proper error handling for already stripped/compressed binaries
- Massive size reduction: 46.1M → 13M (68% reduction)
- zinit: 8.1M→2.2M, rfs: 13M→4.9M, mycelium: 21M→5.3M, corex: 4.0M→1.6M
