Merged

`GET /new` now sends a Server-Timing header that names `session`, `orgs`, `access` and `render`, alongside the usual `app`. I couldn't run the type check: `bun install` and `bun x tsc` both fail in this sandbox with a read-only tempdir error, so the forge's check is the first type check.

GET /new now sends a Server-Timing header that names session, orgs, access and render, alongside the usual app. I couldn't run the type check: bun install and bun x tsc both fail in this sandbox with a read-only tempdir error, so the forge's check is the first type check.

Phases: session is the session time the server already measured. orgs is the read of the user's organisations. access is the per-org write-access check. render is building the form and the page. These use notePhase and timePhase the way src/web/pages/milestones.ts does. The two reads keep their order, and nothing new is computed for the header.
Shape of the change: in src/web/pages/site.ts I moved the owner list out of newRepoForm into a small ownersFor helper, and newRepoForm now takes the owners as an argument. That lets render cover only the building of the page, not the reads.
Unchanged: the page's body, status codes and caching.
Also timed: the 422 re-render in newRepoSubmit goes through ownersFor, so that response carries orgs and access too.
Test: test/new-repo-timing.test.ts signs in, requests /new, and checks that each phase name appears with a dur= value. It checks names only, never a time. It fails without the src/web/pages/site.ts change.
Tests I ran: the new test passes, and so do apps-new and cross-repo-pull, which request /new. I didn't run the whole suite.

To try it, sign in and run curl -sI -b <cookie> $URL/new | grep -i server-timing.

Approved. The change follows the pattern already used in settings.ts, boards-view.ts and forges.ts: session is noted via takeSessionTime, the two reads are timed separately, and render covers only the page build. The body, status and security floor are untouched, and the 422 re-render also carries the phases. The test checks names only, and the type imports are in place. I could not reach the preview from my sandbox, because the proxy denied the host, so this is a source-only review. There is no visible UI change and the design system is not affected.

Two things I would do next:

Fix the test header comment, which cites #3507 where the pull is #3523. Add a case for the 422 re-render of POST /new, which currently has no test for its orgs and access phases.
Move the new route_timing import after the hash-gate import to match the alphabetical order of the neighbouring imports.
