28b2744c67 Release 2.1.3: Fix disk backup corruption, solid PQ encryption, block I/O, and format mismatches 
- 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

62af09ad9c Zupt v2.1.2: add full-disk backup/restore, expand test suite, improve compression handling 
- Introduced full-disk backup/restore (src/zupt_disk.c, ~530 LOC)
  - Backup: streams 4MB blocks with sparse detection and all codecs
  - Restore: per-block checksum validation for integrity
  - Supports password (-p), PQ hybrid (--pq), or no encryption
  - Real-time progress bar with throughput reporting (stderr)

- Implemented sparse detection (8-byte zero scan)
  - Zero blocks stored as STORE (near-zero overhead)

- Added disk-aware safeguards
  - ZUPT_FLAG_DISK_IMAGE prevents misuse with extract
  - Immediate failure on wrong password during first block decrypt

- Cross-platform device size detection
  - Linux: BLKGETSIZE64
  - macOS: DKIOCGETBLOCKCOUNT
  - Fallback: lseek

- Compression behavior
  - ~2928:1 on highly repetitive data
  - ~1.33:1 on random data (auto STORE fallback)

- Expanded test suite to 77 tests:
  - 11 VV unit
  - 13 NIST/RFC vectors
  - 22 regression
  - 14 multi-threaded
  - 10 post-quantum
  - 7 disk (normal, encrypted, PQ, sparse, LZHP, extreme compression, wrong-password)

Release stats:
- 74 files, 168KB, zero .o artifacts
- 77/77 tests passing
- Fully clean under ASAN + UBSan

754be4e84e Zupt v2.1.1: fix cross-arch build issues, eliminate UB, improve Android/Termux support 
- Removed all shipped .o files from tarball (fixes aarch64/Termux linker errors with x86_64 objects)
- Added arch-safety guard in Makefile to auto-detect and remove incompatible .o files
- Switched default compiler from gcc to cc (Termux uses clang)
- Skipped -lpthread on Android (bionic provides pthreads)
- Added Android detection via uname -o
- Fixed Keccak UB: ROL64(x,0) no longer expands to undefined x >> 64
- Achieved zero UBSan/ASAN issues across all PQ crypto paths
- Moved sys/syscall.h include to file scope with proper __linux__ guard

Release stats:
- 73 files, 159KB, zero .o artifacts
- 70/70 tests passing
- Fully clean under ASAN + UBSan

Note: full-disk encryption (--disk) deferred to v2.2.0 (requires raw device I/O, sparse detection, and privilege handling)

06c877ec86 feat: add Jasmin assembly integration for crypto acceleration 
- 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`
