Fusion 979cf115d9 feat(FN-3720): split executor.test.ts into eight focused suites and add she
The merge splits the large monolithic `executor.test.ts` into seven focused test suites covering core logic, pause behavior, prompt handling, recovery, review verdicts, step sessions, and worktree operations, and adds shell context hook plumbing across the dashboard, desktop, and mobile packages to
