Four call sites where #174 (branched from main before the agnes rename
fully landed in some files) emitted or referenced `da fetch`. None are
operator-visible runtime crashes — but `extractor.py` logs a stale
verb to the operator log and `DATA_SOURCES.md` is current docs:
- connectors/bigquery/extractor.py:431,434 (operator-facing log line on
unverified BQ entity_type — was suggesting `da fetch`).
- docs/DATA_SOURCES.md:77,85 (current public docs, two refs to
`da fetch` in the workflow + the BQ scope description).
- tests/test_cli_query_render.py:7 (module docstring listed
`da fetch / agnes schema / etc.` — now `agnes snapshot create / agnes
schema / etc.`).
- tests/test_cli_snapshot_create.py:1 (docstring referenced `(folded
from `da fetch`)` — historical, removed; no value once the rename
landed).
Pre-existing stale `da` references elsewhere in the branch (templates,
operator runbooks, internal comments) are not touched by this commit —
they live outside the merge surface and are a separate cleanup task.
Verified: 10/10 across the affected test files pass.
