v0.20.1

Packages finite PR-manager sessions and scoped unused setup-shell cleanup from #121. Managers preserve durable continuity and decisions, settle descendants, and self-close. Separate five-job review/watch ceilings and zero-slot waiting remain unchanged.

Verification: 367 tests pass; Linux/macOS CI passes; independent authored review approved and eight-scenario decision evaluation completed. Prompt tests do not prove native runtime behavior; no desktop/VPS reinstall is included.

Npm staging workflow: https://github.com/axatbhardwaj/axstack/actions/runs/35562249225 — final registry publication requires maintainer approval.
