feat(02-02): implement pack, unpack, and inspect archive commands
...
- pack: two-pass algorithm reads/hashes/compresses/encrypts files then writes header+TOC+data
- inspect: reads header and TOC, displays all metadata (sizes, offsets, IVs, HMACs, SHA-256)
- unpack: HMAC-first verification, AES-256-CBC decryption, optional gzip decompression, SHA-256 check
- CLI dispatch wired from main.rs to archive module
- Directory traversal protection: rejects filenames starting with / or containing ..
- Compression auto-detection: .apk/.zip/etc stored without gzip (flags=0x00 when no file compressed)
- Round-trip verified: pack+unpack produces byte-identical files
- HMAC tamper detection verified: flipped ciphertext byte triggers rejection
