feat(newsroom): version splash on every release, named in the rollout chart

[RonanHevenor]

You asked for the splash — "welcome to version ___" — and to see it in the pie chart. Both halves already existed in the dashboard and neither knew about the other.

users.latestVersion recorded which release a person had acknowledged, and the admin-only pie chart grouped unretired staff by that field. But the notice that wrote it was hardcoded to 1.0.0 — component copy, gate condition, and API route all. So it announced itself once, in March, and could never fire again. Everyone has been stuck in the 1.0.0 slice ever since.

What changed

VersionSplash replaces NewsroomMovedNotice and renders whatever version is deployed:

Welcome to Polymer 1.1.0 — Indigo! 🎉
Polymer 1.1.0 - Nobody gets their head cut off any more.

• Gate is now latestVersion !== APP_VERSION instead of a literal '1.0.0'
• /api/newsroom/version-notice stamps APP_VERSION instead of '1.0.0'
• Release notes live in RELEASE_NOTES in lib/version.ts

Announcing a release is now a package.json bump plus one entry. Nothing else.

The chart becomes live again

Dismissing the splash is what writes the field the chart counts — so the chart stops being a fossil and starts reading as how many people have actually seen the notes.

Its legend now carries the release name beside the number, falling back to the bare number for unnamed majors:

stored	legend
1.1.0	1.1.0 “Indigo”
1.0.0	1.0.0 “Indigo”
0.0.0	0.0.0
2.3.1	2.3.1

0.0.0 is the bucket for staff who haven't signed in since version tracking began; the name is per major, which is why both 1.x entries read Indigo.

Details

The old route is deleted rather than left behind — nothing else called it. Dismissal closes the modal even if the stamp request fails, so a network error means seeing the notice again next load rather than being trapped behind it.

No migration. users.latest_version has existed in both paths since 20260324_220000.

Verified

• New route 401s unauthenticated; old path is now 404
• Gate shows for 0.0.0 and 1.0.0, hides at 1.1.0
• Legend labels render as in the table above

Note

I could not click through the rendered modal or the chart — that needs a logged-in newsroom session, and I don't enter credentials. The logic above is verified directly; the visual pass is worth a look when you next open /newsroom.

pnpm typecheck clean. pnpm lint 0 errors (53 pre-existing migrations/ warnings, unchanged).
