refactor: model naming v1(base)/v2, Qdrant collection naming

- Phase 1 = v1 (base model, sentence chunk embedding)
- Phase 2 = v2 (full pipeline + 5W1H)
- Naming leaves room for v3, v4, etc.
- Qdrant collection: momentry_dev_v1 (active model under dev)
- Release packaging exports Qdrant points snapshot
