Subject: [PATCH] Add unit tests for useRuntimeFlag composable

8 table-driven tests covering featureDropdownMenu computed:
- versions at, above, and below the 2.11.0 boundary
- v-prefixed and pre-release version strings
- uncoercible strings (dev, unknown) fall back to 0.0.0

Uses a reactive ref mock so Vue's computed re-evaluates on
each it.each entry without needing jest.isolateModules.
