fix: високо и средно приоритетни бъгове в query, protocol, storage, vector, fts
...
Поправени проблеми:
- Wire protocol: bounds checking, max length limits, recursion depth limit
- SQL injection: escape-ване на quotes в exprToSql string literals
- ReDoS: escape-ване на regex metachars в LIKE/ILIKE
- Stale BTree indexes: добавен BTree.remove() + изтриване при UPDATE/DELETE
- SSL: quoteShell за всички shell команди с пътища
- Boolean literals: parser вече разпознава tkTrue/tkFalse
- Unary minus: lowerExpr map-ва ukNeg към irNeg (вместо irNot)
- Non-aggregate UDFs: lowerExpr създава irekFuncCall вместо NULL literal
- UTF-8 FTS: tokenize използва runes вместо байтове
- HNSW: добавен Lock за thread-safe insert/search

feat: production polish — recursive CTE, UNION/INTERSECT/EXCEPT, DROP INDEX, JSON path, FTS SQL, covering index, SCRAM auth
...
- Recursive CTE execution (WITH RECURSIVE + UNION ALL, work-table loop)
- UNION / INTERSECT / EXCEPT parser + executor (nkSetOp)
- DROP INDEX parser + executor
- VIEW DDL persistence via AST-to-SQL serializer
- JSON path operators -> and ->> (lexer, parser, IR, executor)
- FTS SQL wiring WHERE col @@ 'query' (case-insensitive term match)
- Multi-column index range scans (prefix equality + range on last col)
- Covering index optimization (skip LSM read when index covers SELECT)
- SCRAM-SHA-256 authentication (password-based validation)
- 279 tests, 0 failures

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.
