feat(pipeline): add WSCH (Wowee Spell School) catalog

56th open format — replaces SpellSchools.dbc plus the
Resistances.dbc resistance-cap tables. Defines damage
schools spells use: Physical, Holy, Fire, Nature, Frost,
Shadow, Arcane, plus combined / hybrid schools that count
as multiple types simultaneously (Spellfire, Spellshadow,
Spellfrost — relevant for resistance-bypass mechanics).

7 canonical schools with single-bit IDs (1, 2, 4, 8, 16,
32, 64) so combinedSchoolMask values line up directly with
the spell engine's school-bit enum. Hybrid schools use
high-bit IDs (0x80000001+) and their combinedSchoolMask
references the canonical bits they qualify as. Each school
carries visual identity (color tint, icon), gameplay rules
(canBeImmune / canBeAbsorbed / canBeReflected / canCrit),
resistance cap at max level, and cast / impact sound IDs.

Cross-references with prior formats — castSoundId and
impactSoundId point at WSND.soundId; combinedSchoolMask
is a bitmask of OTHER WSCH.schoolId values within the same
catalog.

CLI: --gen-sch (3 base — Physical / Fire / Holy showing
non-resistable Holy + non-reflectable Physical), --gen-sch-
magical (6 canonical magical schools with proper colors
+ 365 max-level resistance caps), --gen-sch-combined (3
hybrids — Spellfire / Spellshadow / Spellfrost with
multi-bit combinedSchoolMask), --info-wsch, --validate-wsch
with --json variants. Validator catches id+name required,
reflected-without-absorbed warning (reflected damage
should be absorbable), self-referential combinedSchoolMask
(school qualifying as itself), and combined-mask references
to bits not defined in the same catalog (resolved at runtime
across catalogs).

Format graph: 55 → 56 binary formats. CLI flag count: 798
→ 804.
