[maria-rcks]

ci run 34659051204 passed all web assertions but failed on an uncaught cancelAnimationFrame is not defined from the file editor language readiness suite. the worker pool queues a final state broadcast during teardown; drain that immediate callback before restoring browser globals.

verification: all 7 tests in the affected suite pass, and targeted lint and formatting pass. this changes only test teardown.

- Line 120: Update the cleanup flow in the file-editor language readiness test
to track pending requestAnimationFrame handles and clear them after pool
termination settles but before vi.unstubAllGlobals() restores globals. Follow
the existing handle-tracking pattern in fileEditorHighlight.test.ts, ensuring
late broadcast callbacks cannot run against restored animation-frame globals.
