feat(pipeline): add WTSK (Wowee Trade Skill / Recipe) catalog

New open format — replaces SkillLineAbility.dbc plus the
recipe portions of SkillLine.dbc plus the AzerothCore
trade_skill SQL tables. Closes the crafting gap left by WSKL
(which carries skill lines but not the recipes that bind to
them).

14 professions (Blacksmithing, Tailoring, Engineering,
Alchemy, Enchanting, Leatherworking, Jewelcrafting,
Inscription, Mining, Skinning, Herbalism, Cooking, FirstAid,
Fishing). Each recipe has 4 skill-up bracket thresholds
(orange / yellow / green / gray) for skill-up probability,
a craft spell cross-ref (WSPL), produced item cross-ref
(WIT) with min/max quantity range, an optional tool item,
and up to 4 reagent slots (itemId + count).

Cross-references with prior formats — craftSpellId points at
WSPL.spellId, producedItemId / toolItemId / reagent[].itemId
all point at WIT.itemId, and skillId points at WSKL.skillId.

CLI: --gen-tsk (3-recipe entry-tier starter), --gen-tsk-
blacksmithing (5-recipe progression rough sharpening through
truesilver champion), --gen-tsk-alchemy (5-recipe progression
minor healing through flask of titans), --info-wtsk,
--validate-wtsk with --json variants. Validator catches
id=0/duplicates, profession out of range, missing craft spell
or produced item, monotonic-bracket check (must be orange <=
yellow <= green <= gray), reagent itemId-without-count
mismatch, and free-recipe warning (no reagents and no tool).

Format graph now exposes 49 distinct binary formats. CLI
flag count: 747 → 752.
