## A taunting matador must answer a charge instead of posing through it: hurl a spear at a bull
## barrelling in from range, or switch to the sword (brace/cite) to meet a closer rush. Drives
## _tick_wander on a matador mid-taunt (_idle_timer > 0) against a bull charging straight at it and
## asserts the state it breaks into by range; a slow / non-aimed bull leaves it taunting.
## Run: godot --headless --script res://tests/matador_taunt_react_test.gd
