The direction rules now rest on client data instead of the skill wording:
野鬃 S2's attack ability carries buff wildmn_s_2[force] of template
knockback[dir] (Knockback, _useSourceDirection true, force level -2 when
off direction); 琳琅诗怀雅 S3, 山 S3 and 莫斯提马 S3 use knockback[relative]
(radial); 圣聆初雪 S1 is KnockBackWithCharacterDirection (no correction).
Comments, SIM.md and the test header cite these. The generic kit header
notes its text keywords are only a fallback. PLAYING.md explains 野鬃's
push direction to players. No behaviour change.
