A repository's builds page speaks the home page's language #9795

The builds page (/:owner/:name/builds) and the pin form (/builds/new) now use the same markup as the home page and the new issue form. Typecheck, the gate and design-lint are clean. test/builds-etag.test.ts passes unchanged. I ran only the builds-related test files, not all of bun test.

• Builds page: The card( blocks are gone, including the one on the "Opening preview" page that Preview lands on. There is a "Builds" <h2>, and "Pin a build" and "Iterations" sit under it as plain links. Each build is a row() in <ul class="list builds">, indented by lineage depth.
• Each row: The label is the one accent link, to the commit. The trail holds the quiet links: Screenshots, the cart link where there is one, Preview and Delete. Delete is muted until hover or focus turns it red. Preview is a link-style button inside its POST form, so it still works as before. With no builds it says "No builds yet." and, for a writer, points to a branch to pin from.
• Pin form: It now has an <h1>, the .narrow-wide wrapper and .form-actions, with Cancel as a link, and the Note field is a textarea.
• Docs: docs/design/areas/builds.md records the shape.
• New test: test/builds-rows.test.ts checks the empty sentence, the <ul class="list builds"> rows and no .card. It would fail on main.
• Changed test: I edited the lineage assertion in test/iterations.test.ts. It matched the old class="build-row" markup and now matches <li data-depth="N">, so it is no longer an unchanged test.
• Changed wording: The Preview link says "Preview" instead of "Preview now", and the empty text changed from "No pinned builds".
• Left alone: The shots and cart pages under /builds/:label.
• Plan: The keep_plan tool wasn't available in this run, so there is no plan on the issue.

To try it, open /<owner>/<repo>/builds and /builds/new on the pull's preview.

I pushed a second commit, and it should clear the failed check. The gate wanted a Try: line in a commit message for this pull, and none of my commits had one. This commit has no code changes. I haven't seen the forge's check run on it yet.

The builds page now uses the home page's markup. Each build is a row in a plain list, and the pin form matches the new issue form.

• Changed: src/web/pages/builds.ts is rewritten. The three card( blocks are gone. The label is the one accent link, and Preview and Delete are quiet links in the trail. docs/design/areas/builds.md records the shape.
• Tests: The new test/builds-rows.test.ts checks the rows and that no .card appears, and it fails on main. I edited one assertion in test/iterations.test.ts, because it matched the old class="build-row" markup. test/builds-etag.test.ts passes unchanged.
• Not changed: The shots and cart pages under /builds/:label.

Try: Open /trevato/forge/builds and /trevato/forge/builds/new on the preview. You should see list rows with no cards, and a pin form laid out like the new issue form.

All four of sentinel's points are fixed and pushed. Typecheck, the gate, design-lint and the builds-rows, builds-etag and iterations tests pass. I didn't run the full suite.

1. Quiet trail: Screenshots, the cart link, Preview and Delete are all muted now, with an accent hover. Delete turns --danger on hover or focus. "Pin a build" and "Iterations" under the <h2> are muted too, so the row label is the only accent link.
2. Pin form test: /builds/new is checked for the <h1>, .narrow-wide, .form-actions and no .card. Cancel is checked as an <a>.
3. Writer rows test: the new test renders the list as a writer. Preview must be a button inside a POST form to /builds/preview, and Delete a link to /-/confirm. A reader's render must show neither. I call the render function directly with a made-up pin, because a real Preview needs an app set up first.
4. Cleanup: the extra blank line is gone, and buildsCard is now buildsList. Nothing outside builds.ts imported it, and the iterations lineage test was already updated for the new <li data-depth="N"> markup.

Try: open /trevato/forge/builds as a writer and check that the trail links stay grey until hover. Then open /builds/new and compare it with the new issue form.
