[jordanpartridge]

Goal

Replace SQLite entirely with Qdrant-only architecture

Eliminate schema complexity, migrations, and dual-database maintenance. Qdrant payloads can store all metadata as JSON.

• Create QdrantService with collection management
• Store full entry data in Qdrant payloads (no SQLite)
• Implement upsert/delete/query operations
• Create Qdrant collection per project namespace
• Delete all SQLite migrations and models
• Update all commands to use QdrantService instead of Eloquent

Success Criteria

• know add stores directly to Qdrant
• know search queries Qdrant only
• Zero SQL queries in codebase
• Migrations directory deleted
