fix(ci): rerun saved Feature Stacks safely

[lopugit]

Summary

• omit completed and draft PRs when a reusable saved Feature Stack is run again, while preserving the remaining live order
• require the signed target-merge heartbeat before marking the saved stack terminal
• negotiate saved-stack capability 1.2.0 and update docs/checklists

Validation

• 15 focused Feature Stack and capability tests pass
• production Vercel output build + verifier pass
• full TypeScript still reports the existing repository-wide baseline; no errors remain in touched files
