test_undo_redo_lifecycle in tests/test_undo_redo_sim.py was failing in
the live_gui batch (passes in isolation) because btn_reset
(_handle_reset_session) was not clearing the HistoryManager's undo and
redo stacks. Prior tests in the same live_gui session leave stale
entries that interfere with tests that assume btn_reset provides a
clean history baseline.
Adds clearing of:
- app.history._undo_stack
- app.history._redo_stack
- app._last_ui_snapshot (None so the next take sets the baseline)
- app._pending_snapshot (False so debounce starts fresh)
- app._state_to_push (None so no stale state queued for push)
at the end of _handle_reset_session. The App is reached via
self.hook_server.app (set during _init_ai_and_hooks); all accesses are
guarded with hasattr/getattr for safety when the hook_server isn't
initialized yet (tests that construct AppController without starting
services).
Tests: test_undo_redo_lifecycle, test_undo_redo_discussion_mutation,
test_undo_redo_context_mutation all pass (3/3). The previously-failing
batch context also passes (verified with 14 tests from the gw7 worker
plus the test_undo_redo_sim set).
