fix: критични бъгове в storage, MVCC, auth, Raft, query executor
...
Поправени проблеми:
- MVCC: aborted транзакции вече не стават видими (добавено abortedTxns множество)
- LSM-Tree: поправена загуба на данни при immutable memtable overwrite
- LSM-Tree: поправена SSTable search order (сортиране по id вместо minKey)
- WAL: sync()/close() вече извикват posix.fsync()
- Auth: simpleHash (djb2) заменен с HMAC-SHA256
- Recovery: summary() вече не мутира базата данни
- Raft: поправена majority calculation за четен брой нодове
- Query: EXISTS subqueries вече изпълняват подзаявката
- Nimble: поправен build (-d:ssl) и bench task
Добавен BUG_AUDIT.md с пълен доклад и план за подобрения.
292 теста, 0 failure-а.

feat: production blockers — JOINs, deadlock detection, TLS, parameterized queries
...
- JOIN execution: INNER/LEFT/RIGHT/FULL/CROSS with column disambiguation
- Deadlock detection: wait-for graph wired into TxnManager.write()
- TLS/SSL: OpenSSL via std/net for TCP wire protocol, auto self-signed certs
- Parameterized queries: ? placeholders with WireValue binding
- Wire protocol: mkQueryParams message support
- HTTP /query endpoint accepts JSON params array
- Nim client: query(sql, params) overload
- Tests: 262 passing (15 new)
All PLAN.md production blockers resolved.

feat: integrate hunos web server + jwt-nim-baraba + real WAL recovery + compaction
...
HTTP Server:
- Replaced asynchttpserver with hunos (multi-threaded, trie router, CORS middleware)
- JWT authentication via jwt-nim-baraba (HS256 with BearSSL crypto)
- POST /query, GET /health, GET /metrics, POST /auth, GET /api (OpenAPI spec)
- Proper CORS headers via hunos corsMiddleware
WAL Recovery:
- recover() now actually applies committed entries (REDO)
- Skips uncommitted entries (UNDO)
- Takes optional LSMTree parameter to apply recovery
SSTable Compaction:
- Real compaction: reads SSTable entries, merges by key (newest wins), writes merged file
- Deduplication: keeps only newest version per key
- Tombstone cleanup: removes deleted entries
- Old SSTable files deleted after merge
Dependencies:
- Added hunos >= 1.2.0 and jwt >= 2.1.0 to nimble
SSTable fields exported for compaction access.
All 216 tests pass
