ed ff523f7e6e fix(test_api_generate_blocked_while_stale): sleep in monkeypatches to keep switch in-flight
The test had a pre-existing race: it monkeypatched
_rebuild_rag_index and _flush_to_project to no-ops, which made
_do_project_switch complete synchronously inside the io_pool
worker. By the time the test's _api_generate call ran
is_project_stale() was already False (the worker had cleared
_project_switch_in_progress), so the 409 contract was never
exercised.

Fix: replace the no-op lambdas with `lambda: time.sleep(0.5)`.
This keeps the worker busy for 500ms, which is more than enough
window for the test to call _api_generate and observe the
stale flag. _wait_for_switch then drains the rest of the work.

Also: removed the @pytest.mark.skip marker; the underlying issue
is now fixed in the test.

Verified: 9/9 in tests/test_project_switch_persona_preset.py pass
(previously 8 passed + 1 skipped).
