Ensure loader closes Qdrant client between runs

[Teagan42]

What

• wrap the loader's Qdrant client usage in a try/finally so it always closes after each run
• extend the integration test harness to track client shutdowns and assert a single close per run
• bump the project version to 2.0.7 and sync dependency manifests

Why

• ensure Qdrant client resources are released even when runs fail, and verify the behavior with automated coverage

Affects

• loader pipeline orchestration and loader integration tests

Testing

• uv run pytest tests/test_loader_integration.py

Documentation

• not required
