BUFFA KILLS CHANGELOG CONFLICTS WITH FRAGMENT FILES

Buffa switched to changie's fragment model, eliminating the merge queue bottleneck that turned every PR into a manual rebase.

The shift moves changelog entries from a single `CHANGELOG.md` file to per-PR fragment files under `.changes/unreleased/` [1][2]. Since each PR now adds a new file instead of modifying shared lines at the top of the changelog, merge conflicts vanish. The change ships with two separate review commits: the core fragment migration and a follow-up that pins changie's SHA256 in CI to prevent execution of tampered upstream releases [3]. Across the plugin ecosystem, routine SHA bumps continue rolling in steady: `claude-plugins-community` picked up updates to five plugins [4][5][6][7][8], while `knowledge-work-plugins` bumped auth0, langfuse, and carta-investors [9][10][11]. Two new plugins are in flight: canva and tavily are landing in both `knowledge-work-plugins` and the official marketplace [12][13][14][15]. Meanwhile, buffa's scope guard exemption for the bump bot [16][17] ensures automated SHA updates don't trip the external-PR validation that requires additions-only changes to `marketplace.json`. Buffa also documented its generated struct evolution policy [18][19], clarifying that new fields may appear on generated structs and exhaustive destructuring is not semver-protected.
