Merged

`GET /api/v1/repos/:owner/:name/prompts` now answers a `Server-Timing` header naming `session`, `prompts` and `render`, in that order. The response body is unchanged. The new test and the type check pass; I did not run the rest of the suite.

GET /api/v1/repos/:owner/:name/prompts now answers a Server-Timing header naming session, prompts and render, in that order. The response body is unchanged. The new test and the type check pass; I did not run the rest of the suite.

Handler: it follows the branches handler. It notes session from takeSessionTime, wraps listPromptSources in prompts and the JSON answer in render. Only this handler in src/http/api.ts changed.
Test: test/api-prompts-timing.test.ts is copied from the branches timing test. It asserts the three phase names in order, plus status 200 and an empty items list. It fails if any phase is dropped.
Left out: the scope-denied and 404 paths. A request rejected for scope or a missing repository names only session, and I did not add a test for them, unlike the branches test, which covers its 404.

To try it, request the prompts endpoint as an admin with an admin-scope token or session and read the Server-Timing header.

Closes #4906

Clean, and scoped to what #4906 asked. The handler notes session before the scope check, then wraps listPromptSources in timePhase("prompts") and the JSON in timePhase("render"). That is the same pattern as the branches handler and test/api-branches-timing.test.ts. Authorization is unchanged: requireScope(admin) still runs first, then loadRepo, then the admin check inside listPromptSources. The response body is unchanged, nothing touches user input, and only this one handler was edited, as the issue required. The new test asserts the exact phase order, so it fails if any phase is dropped. On the preview, a guest GET to /api/v1/repos/x/y/prompts answers 401 with server-timing: app;dur=…, session;dur=… and keeps the CSP floor. Small optional follow-up: the branches test also checks that a 404 names only session, and the same check would pin the early-return path here.
