Summary by Sourcery

Adopt shared Namespace runners for compatible utility workflows while preserving capacity for build and coverage jobs.

Enhancements:

• Add workflow runner contracts to prevent approved runner assignments from drifting.

CI:

• Configure actionlint to recognize the shared Namespace runner label.

Documentation:

• Document GitHub Actions runner profiles, cache behavior, and the retained build and coverage runner exception.

Tests:

• Add contract tests covering shared Namespace assignments and capacity-sensitive runner retention.

Reviewer's Guide

The PR adopts the shared uncached namespace-profile-default runner for the audit and delayed-comment workflows, keeps build and coverage workloads on ubicloud-standard-8 because of their capacity requirements, documents these runner contracts, and adds actionlint/test coverage to prevent assignment drift.
