feat(pipeline): WCRA crafting recipe catalog (133rd open format)

Novel replacement for the implicit recipe expansion vanilla WoW
carried in SpellReagents.dbc + Spell.dbc effect-24 (CREATE_ITEM)
+ per-trade-skill SkillLineAbility rows. Each WCRA entry binds
one trade-skill recipe spell to its variable-length reagent
list (itemId+count pairs, vanilla cap 8, format cap 32),
produced-item id + count, the trade skill it belongs to, the
minimum skill level to cast, and the source item that teaches
the recipe.

Three presets seeded with canonical vanilla item/spell IDs:
  --gen-cra-alchemy        4 potions (Minor/Lesser Healing+Mana,
                            Greater Healing, Major Mana) using
                            herb itemIds 2447/765/2450/3357/etc
                            and Empty Vial / Crystal Vial
  --gen-cra-engineering    3 recipes including Target Dummy with
                            5 reagents (variable reagent count
                            demonstration); learnedFromItemId
                            references the recipe blueprint
  --gen-cra-blacksmithing  3 recipes covering low/mid/high tiers
                            (skill 1 / 50 / 235) including Heavy
                            Mithril Helm with 4 different bar/ore
                            reagents

Validator catches: id+name+spellId+tradeSkillId+producedItemId+
producedCount required, no duplicate recipeIds, no duplicate
spellIds (cast-handler conflict — two recipes responding to the
same cast), no zero-itemId/zero-count reagents, no duplicate
reagent itemIds within a single recipe (should be merged into
single entry with summed count), no self-reagent (recipe
consuming its own produced item is a perpetual-motion bug).
Warns on requiredSkillLevel > 450 (above WotLK cap) and empty
reagent list (free-to-craft is unusual but allowed for some
alchemy transmutes).

Format count 132 -> 133. CLI flag count 1391 -> 1398.
