feat(pipeline): add WSVK (Wowee Spell Visual Kit) catalog

47th open format — replaces SpellVisualKit.dbc +
SpellVisualEffectName.dbc plus the AzerothCore-style spell
visual SQL data. Defines per-spell visual presentations:
cast-bar effect model, projectile model + travel speed +
arc gravity, impact effect model, hand effect on the caster,
and the animations + sounds that fire at cast / channel /
impact time.

Cross-references with prior formats — castAnimId / impactAnimId
/ precastAnimId point at WANI.animationId, castSoundId /
impactSoundId point at WSND.soundId. Spell catalogs (WSPL)
will reference visualKitId here to bind "what mechanically
happens" to "what plays visually."

CLI: --gen-svk (3-kit Frostbolt/Fireball/HealingTouch starter
showing projectile + AoE + heal patterns), --gen-svk-combat
(5 melee/ranged with WANI animation refs), --gen-svk-utility
(4 portal/hearth/mount/resurrect with no projectile),
--info-wsvk, --validate-wsvk with --json variants. Validator
catches id=0/duplicates, missing name, negative speeds/radii,
projectile-model + speed coherence (model without speed =
never travels; speed without model = invisible), and a
no-effect catch-all (no models + no anims + no sounds).
