feat(pipeline): add WGLY (Wowee Glyph) catalog

42nd open format — replaces GlyphProperties.dbc + GlyphSlot.dbc
plus the AzerothCore-style glyph_properties SQL table. Defines
the WotLK glyph system: per-class inscribable glyphs that
modify spell behavior. Each entry pairs a glyph item (the
inscriber's craft output) with the spell aura that applies the
modification, tagged with a Major / Minor / Prime slot type and
a classMask of allowed classes.

Cross-references with prior formats — spellId points at
WSPL.spellId (the aura), itemId points at WIT.itemId (the
inscribed item), and classMask bit positions match the WCHC
classId enum (1=Warrior, 2=Paladin, 3=Hunter, etc).

CLI: --gen-glyphs (3-entry per-role starter), --gen-glyphs-warrior
(6-entry full warrior allotment), --gen-glyphs-universal (4
classMask=All utility glyphs), --info-wgly, --validate-wgly with
--json variants. Validator catches id=0/duplicates, empty name,
spellId=0 (glyph applies no aura), classMask=0 (no class can
inscribe), itemId=0 warning, requiredLevel<25 warning (below
WotLK glyph threshold), and glyphType out-of-range.
