feat: centralize package quarantine policy

[jan-kubica]

Summary

• delegate pull-request quarantine validation and schedule-only exception pruning to immutable shared workflows
• enforce five-day age checks for registry packages introduced relative to the target-base lockfile
• serialize prune mutation runs per repository and retain least-privilege caller permissions
• remove the expired Bun exception and timestamp permanent first-party exclusions where present

Verification

• shared quarantine policy checker
• actionlint
• git diff --check
• repository tests
