Hitbox now builds a DamageEvent (cause + hit position + shaped knock-up) and calls the bull's new receive_damage(), instead of two stringly Object.call()s. receive_damage adapts over the existing pip/knock-up logic so behaviour is identical -- the characterization test drives both the string and typed paths and asserts the same outcomes. Wire fx/damage/harness tests into run_tests.sh + CLAUDE.md. All hitbox guard tests green (stab, bear hitbox, ram, charge).

## The one typed payload for every hit in the game — a bull goring a matador, a bear slam popping
|
|
## the bull, a thrown spear landing. It replaces the scattered, stringly Object.call(&"take_sword_hit",
|
|
## "gored") paths: an emitter (a Hitbox) fills one of these and hands it to the target's
|
|
## receive_damage(event). One shape to read, log and type-check, instead of four call conventions.
|
|
##
|
|
## It serves both victim models the game already has: the bull, which dies on one clean hit
|
|
## (lethal + cause + hit_position), and an enemy, which is launched/ragdolled by an impulse
|
|
## (knockback_dir · knockback_strength + knock_up). A given hit just leaves the fields it doesn't
|
|
## use at their defaults.
