gsxdsm a768d36dae FN-6817: root reliability fixtures under worker temp

Reliability interaction fixtures now stay inside the Vitest worker temp root to avoid merge-reuse worktree collisions.

- Add a helper that prefers FUSION_TEST_WORKER_ROOT for reliability fixture roots.
- Verify fixture git initialization before tests use generated repositories.
- Clean up the paired worktree root during fixture teardown.
- Cover the worker-root placement and worktree-root cleanup behavior in the merge runner preflight test.
