Accepted agent delivery; branch-keyed search descriptor included.

---

Summary by cubic

Prepares the v0.62.0 release: folds all pending next release-note fragments into a single .alfonso/release-notes/v0.62.0.md and points the OpenCode and Pi plugin upgrade announcements at 0.62.0, with a search-quality slice descriptor for the release branch.

Confidence Score: 5/5

This release-notes PR appears safe to merge.

Summary

Consolidates pending release notes into v0.62.0.md and refreshes both plugins’ announcements.

• AFT 0.62.0 release notes gather shipped features and fixes in one page.
• OpenCode and Pi plugins announce AFT 0.62.0 highlights.
• The release-notes benchmark slice is marked as non-ranking harness work.
