gsxdsm 20184acdfd FN-7486: fix no-diff merge recovery ownership checks ...

Fix no-op task branch recovery by recognizing canonical branches with no unique diff before rejecting inherited foreign trailers.

- Add no-diff ownership classification for already-merged detection when canonical task branches inherit another task's landed commit.
- Teach self-healing and branch-misbound recovery to ignore foreign branch-tip trailers only for branches proven to have no unique task diff.
- Skip synthetic verify:fast typechecks for JavaScript alias packages without tsconfig files and cover the behavior with tests.
- Add regression coverage and a patch changeset for the recovery fix.
