Guardrail to build

Add release metadata and changelog coverage checks tied to the package or deploy artifact that changed.

Representative feedback

• p1 evalops/deploy#4193 top-level feedback
  • Follow-up: addressed the P1 BigQuery schema migration review. The new queue telemetry fields now append to internal_runner_diagnostics_raw.json instead of being inserted before failure_count, matching BigQuery existing-table schema update rules. Added a regression test for the append-only field order and reran focused diagnostics tests.

Acceptance criteria

• The class has an owner repo and a concrete guardrail location.
• The guardrail fails for at least one representative feedback shape listed above.
• The guardrail is wired into the smallest relevant CI or preflight target.
• The issue is closed only after the guardrail has merged and the feedback sentinel no longer ranks this class as an unaddressed candidate.
