fix: stabilize release CI regression tests

Address Desktop CI 35849362694 failures with isolated OpenCode config dependencies, cleared IPC lookup counts, Supervisor default-off expectations, and polling-safe UI fixtures and timeouts.

Record the failed candidate CI and follow-up validation: 14 focused tests, typecheck, and lint passed. Product code, versions, and bilingual release notes are unchanged. The revised candidate requires approval and successful main-branch CI before tagging.
