fix: resolve all 55 identified bugs across the codebase

Browse Source 
Comprehensive bug fix pass across all subsystems:
- Critical: lexer infinite loop, WAL lock discipline, checkpoint safety,
  compaction verification, HMAC key truncation, healthCheck leak
- High: MVCC lock safety, B-Tree delete rebalancing, Raft stale term
  handling, replication socket leaks and ack cleanup, sharding migration
  with old assignments, 2PC recovery, JWT/SCRAM auth fixes, wire protocol
  bounds checks
- Medium: config error handling, MERGE parser completeness, IR/codegen
  correctness, UDF bounds checks, LIMIT cost accuracy, mmap safety
- Low: timeout handling, float parsing edge cases, uint32 truncation,
  cache entry cleanup
