A repository's home names its Server-Timing phases on both paths, the code home and the app home, and /alice/forge leaves the sweep's debt list #5414

For: repoHome (src/web/pages/repo.ts:923) answers with codeHome for a plain repository and studioApp for one with an app. The sweep still lists /alice/forge against #3325, which is closed, so one of the two paths answers with app time alone.

Done:

• [ ] Find which path the sweep's fixture takes and name its phases: session, each read, and render. If both paths lack phases, name both.
• [ ] /alice/forge leaves UNNAMED in test/server-timing-sweep.test.ts.
• [ ] A new test/repo-home-paths-timing.test.ts asserts the phase names for a plain repository and for an app repository, and fails without the change. Bodies are unchanged.

Files: src/web/pages/repo.ts and/or the studio app home module, test/server-timing-sweep.test.ts, the new test.
