Test	tests/test_abilities_complex.py::TestOseInsanity::test_insanity_cannot_trigger_gear_on_allied_target

Tests interaction between Ose, Flauros, Duban.

Preconditions

• P1 Main Phase, P1 has 6 AP

• Lane 0: P1's Ose (#089) — READIED

• Lane 0: P1's ally with only a gear ability (mocked)

Action

• Ose uses Insanity on the ally

• Ally's only ability is gear-timed → blocked → no bonus action

        # Use Flauros (#013) as the ally and give it a mock gear ability
        # Flauros has no registered abilities in abilities_actions by default
        # Register at idx=0 as a gear ability — but we need the ability data
        # to have timing="gear". The handler is registered but can_use_ability
        # checks the data. Let's just check via the timing validation directly.

        ose = make_demon("089", lane=0, owner=Side.PLAYER_1)
        flauros = make_demon("013", lane=0, owner=Side.PLAYER_1)

        state, placed = _make_state_with_demons(ose, flauros, enemy, ap=6)

        rng = DeterministicRNG(42)

        # Capture P1 AP before
        ap_before = state.players[Side.PLAYER_1].ap

        result = execute_ability(
            state, ose_p, ability_idx=0,
            targets=[flauros_p],
            rng=rng,
        )

        # If Flauros has no legal non-gear abilities, the bonus action is a no-op.
        # Check that Insanity's current_player swap doesn't enable gear actions.
        # The key check: current_player should be restored to P1 after Insanity.

Expected Postconditions

• ignore_exhaust/ignore_ready still present (not consumed — no action executed)

• P1 AP unchanged by bonus action
