- Corrected LZHP prediction encoding in disk backups to prevent data corruption
- Disabled spurious SOLID flag for per-block disk archives
- Shared write_enc_header() across all encryption paths to eliminate format mismatches
- Enabled solid compression with PQ encryption support
- Updated block device restore to use O_SYNC + fsync/sync
- Improved Termux/Android host detection for safer builds
- Made zupt_w8(), zupt_w16le(), zupt_w64le() non-static for shared use
- Integrated `zupt_mac_verify_ct` in `zupt_decrypt_buffer()` to replace C XOR loop for HMAC-SHA256
- Integrated `zupt_ct_select_32` in `zupt_mlkem768_decaps()` to replace C `cmov()` for FO transformation
- Added `include/zupt_jasmin.h` with extern declarations and ABI docs
- Added `#ifdef ZUPT_USE_JASMIN` guards with clean C fallbacks in `zupt_crypto.c` and `zupt_mlkem.c`
- Makefile now auto-detects `jasmin/*.s`, assembles and links with `-DZUPT_USE_JASMIN`
Closes#3
