3 new test files that drive the upcoming cli/error_render.py module
and the V2ClientError refactor.
tests/test_cli_error_render.py — 5 cases for `render_error(status, body)`:
recognize cross_project_forbidden BqAccessError shape; recognize
remote_scan_too_large guardrail rejection; recognize
bq_path_not_registered RBAC denial; fall back to truncated form for
unrecognized shape; pass through string `detail`.
tests/test_cli_query_render.py — V2ClientError must use the new renderer:
multi-line output instead of `f"HTTP {code}: {body}"`; no
pre-truncation that would hide the hint field; RemoteQueryError
already carries `details` (smoke).
tests/test_remote_query_error_details.py — audit lock-in for
RemoteQueryError raise sites that already populate details
(blocked_keyword) plus the shape contract for local-validation paths.
Run: 5 errors (cli.error_render module missing — clean ImportError),
2 assertion failures (V2ClientError single-line output, blocked_keyword
detail shape pre-existing). 3 regression-green pass for trivial
reasons; will exercise real code paths once GREEN lands.
