Tom Boucher d9d16551b7 fix(#4091): publish update-check cache via atomic temp+rename (#4313)
* test(#4091): RED — worker cache write must be rename-atomic

Structural regression guard: gsd-check-update-worker.js must not write the
shared per-package cache in place; assert temp+rename publish shape plus a
behavioral no-residue e2e.

* fix(#4091): publish update-check cache via atomic temp+rename

writeFileSync on the shared per-package cache truncates before writing, so
concurrent cross-runtime readers (statusline/banner) could see a torn or
empty record. Stage under a unique same-directory temp and rename into
place — POSIX rename(2) is atomic, so readers see the old or new record,
never a partial one. Degrade policy (#3582) unchanged: errors swallowed,
temp best-effort removed.

* refactor(#4091): hoist temp path, tighten uniqueness assertion (review)

* changeset(#4091): add fragment (pr backfill to follow)

* changeset(#4091): backfill PR 4313

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
