Стабилизация на storage слоя — 6 фази
CI / test (push) Has been cancelled
CI / verify (push) Has been cancelled
Clients CI / build-server (push) Has been cancelled
Clients CI / test-python (push) Has been cancelled

Фаза 1: SSTable Integrity
- SSTable v3 формат с CRC32 footer (data/index/bloom CRC)
- Нов модул storage/crc32.nim (zero-dep, IEEE 802.3)
- verifySSTable() — проверка на magic, version, CRC
- loadSSTable strict mode — отхвърля корумпирани файлове
- newLSMTree логва [WARN] при corrupt SSTables
Фаза 2: baradb repair
- Нов модул tools/repair.nim
- Сканира SSTables, проверява CRC, премества битите в corrupt/
- WAL replay (CrashRecovery) за възстановяване на данни
- CLI: ./baradadb repair --data-dir=... [--dry-run]
Фаза 3: MANIFEST File
- Atomic write MANIFEST (tmp + rename)
- newLSMTree зарежда от MANIFEST, fallback към walkDir
- checkStorageConsistency() — orphan/missing detection
- flushUnsafe и compaction записват MANIFEST
Фаза 4: WAL Rotation & Incremental Backup
- WAL segment rotation при 64MB (wal_archive/wal.000NNN.log)
- maybeRotate() на всеки 1000 записа + при flush
- backup incremental — архивира MANIFEST + SSTables + WAL
- CRC verification на SSTables преди архивиране
Фаза 5: Online Consistent Backup
- checkpoint() — freeze memtable + flush + WAL rotate
- ./baradadb checkpoint — offline consistent snapshot
- backup --online — checkpoint + incremental backup
Фаза 6: SSTable Version Migration
- SSTable.fileVersion поле
- listLegacySSTables() — намира v1/v2 файлове
- migrateSSTable() — пренаписва към v3 (tmp + rename)
- ./baradadb migrate [--dry-run] — offline migration
Документация:
- Обновени docs/en/backup.md, docs/bg/backup.md
- Обновени docs/en/storage.md, docs/bg/storage.md
- Добавени тестове в tests/test_all.nim
