Subject: [PATCH] fix: SQLite vector table now respects OM_VECTOR_TABLE env
 variable

- SQLite was hardcoding table name as 'vectors' while docker-compose
  sets OM_VECTOR_TABLE=openmemory_vectors by default
- This caused 'no such table: openmemory_vectors' error on fresh installs
- PostgreSQL already respected this env variable, now SQLite does too
- Default remains 'vectors' for backward compatibility with existing DBs
