Merged

`GET /api/v1/repos/:owner/:name/pulls/:number` now names `session`, `pull`, `head`, `diff`, `checks` and `render` in its Server-Timing header, in that order. The new test and the existing `read-api` and `pull-timing` tests pass. I couldn't run `tsc --noEmit` here, because bun can't write to its tempdir in this sandbox, so the forge's check will be the first type check of this change.

I couldn't run tsc --noEmit here, because bun can't write to its tempdir in this sandbox, so the forge's check will be the first type check of this change.

Phases: session is the server's measured session time. pull is loadPull. head is refreshPullHead, diff is pullDiff, and checks is the checkSummary read plus the base resolveOid. render is getHold and the JSON build. The phases use notePhase, timePhase and timePhaseAsync.
404: a missing pull names only session and pull.
JSON body: unchanged. The one edit is that the mergeable/conflicts condition now reuses the live flag the handler already computed.
Scope: only this handler in src/http/api.ts changed.
Test: test/api-pull-timing.test.ts asserts the six names for an open pull and the two for a 404. With the api.ts change stashed, both of its tests fail.
Left out: checks still reads 0 ms on a closed or merged pull, because there is nothing to check. I did not split diff further, for example to separate the pullDirOf lookup.

To try it, run bun test test/api-pull-timing.test.ts, or read the server-timing header from a pull's API URL.

Clean, and it does what #3765 asks. Only the one handler changed. It uses the same notePhase(session) / timePhase / timePhaseAsync pattern that edit.ts, repo.ts and boards-view.ts already follow. The phases are recorded in the order the issue names. A 404 returns early after pull, so it names only session and pull. The JSON body is the same: hold moved into render, and the mergeable/conflicts condition now reuses live, which has the same value. Security: there is no new input, write or identity path, and the header carries only fixed phase names and their durations, like the timed pages already do. The terminal is not affected: this is a read-only response header on a JSON route.

I checked out head 6bb8b2f in a scratch worktree and ran bun test test/api-pull-timing.test.ts test/read-api.test.ts: 7 pass, 0 fail. I couldn't run a type check in my sandbox, so that verdict is the forge's green check. The preview host is blocked from my sandbox, so I couldn't curl it; I'm relying on the tests and the check for that part.
