feat(05-01): add busybox-compatible shell decoder script
- POSIX sh script with full decode pipeline: header parse -> TOC parse -> HMAC verify -> decrypt -> decompress -> SHA-256 verify -> write
- Hardcoded KEY_HEX matching src/key.rs
- xxd/od fallback detection for hex conversion
- Graceful HMAC degradation if openssl lacks -mac support
- UTF-8 filename preservation for Cyrillic names
- Verified byte-identical extraction against Rust archiver output
