The claim page's Server-Timing names its phases: session, each read, render #3544

GET /claim now sends a Server-Timing header with session, spawned, owners and render after app. I couldn't run the type check: bun x tsc fails in this sandbox with "bun is unable to write files to tempdir: ReadOnlyFileSystem". The forge's check will be the first type check.

• Phases: claimFragmentPage in src/web/pages/claim.ts uses notePhase, timePhaseAsync and timePhase, the way milestones.ts does.

- session is the time resolving the session took. - spawned is the read of parent.json and the organisation (spawnedOrg). - owners is the Owners team and the spawner's membership. - render covers building the page.

• Unchanged: the body, the status codes and the caching. The reads run in the same order, with the same early dead(ctx, "unknown") return. The one change to the page logic is that owners() now runs before the page is built rather than inline. Nothing new is computed for the header.
• Test: test/claim-timing.test.ts sets up a spawned forge (an org plus parent.json), requests /claim, and asserts each phase name appears with a dur= value. It checks names only, never a time. It fails without the change (checked by stashing the source). claim-link.test.ts still passes with it.
• Left out: the dead-link and POST paths carry no phases, since the issue names only claimFragmentPage. No other page is touched.

To try it, run curl -sI <spawned forge>/claim and read server-timing.
