feat(pipeline): add WANI (Wowee Animation) catalog

46th open format — replaces AnimationData.dbc plus the
hard-coded animation-id tables in M2 model loaders. Defines
named animations (Stand, Walk, Run, Cast, Death, MountIdle,
Fly, ...) with fallback chains, behavior tier (default /
mounted / sitting / aerial / swimming), and weapon-flag
bitmasks that select the correct animation variant when the
model wields 1H / 2H / dual / bow / rifle / wand / etc.

Cross-references with prior formats — fallbackId resolves
within the same WANI catalog (graceful degradation when the
requested animation is absent: Run falls back to Walk,
Attack2H falls back to Attack1H).

10 weapon-flag constants + 6 behavior flags (Looped,
BlendableCycle, Interruptable, MovementSync, OneShot,
PreserveAtEnd). 5 behavior tiers. CLI: --gen-animations
(5 essentials), --gen-animations-combat (8 weapon-typed
attacks + parry + channel), --gen-animations-movement (6
locomotion anims with tier transitions). Validator catches
id-uniqueness, fallback-self-loop, looped-without-duration,
mutually-exclusive Looped+OneShot flags, weaponFlags=0
warning, and unresolved fallback warnings.

Also extends --list-formats and --info-magic with WANI.
