- config_loader: add base_gin_files() to exclude dataset-specific
pipeline_*.gin variants from default `python -m src.main` load
(pipeline_uav_visloc.gin was overriding pipeline.gin)
- main.py: use base_gin_files() in the --gin override branch too
- pipeline.gin: source None (both DB + query) — was 'query',
which silently dropped all DB satellite crops from discovery
- README/CLAUDE/docs: sync source default, tensor format spec
