feat(pipeline): add WPCN (Wowee Player Condition) catalog

49th open format — replaces PlayerCondition.dbc plus the
AzerothCore-style condition resolver. Defines reusable
boolean checks that other catalogs reference by conditionId
to gate gossip options, vendor items, quest availability,
achievement criteria, spell trainer offerings.

16 condition kinds (Always, Race, Class, Level, Zone, Map,
Reputation, AchievementWon, QuestComplete, QuestActive,
SpellKnown, ItemEquipped, Faction, InCombat, Mounted,
Resting), 8 comparison ops (==, !=, >, >=, <, <=, in-set,
not-in-set), and 4 chain ops (none, and, or, not) — chain
multiple conditions via chainNextId to express arbitrary
boolean trees.

Cross-references with prior formats — targetIdA is
polymorphic by conditionKind: resolves to WCHC raceId/classId,
WMS areaId/mapId, WFAC factionId, WACH achievementId, WQT
questId, WSPL spellId, or WIT itemId. chainNextId resolves
within the same WPCN catalog.

CLI: --gen-pcn (3 single-check starters), --gen-pcn-quest-gates
(4 cross-format quest gates with real WQT/WFAC/WACH/WMS IDs),
--gen-pcn-composite (3 leaves + 3 chained roots showing AND/
OR/NOT). Validator catches id=0/duplicates, kind/op out of
range, chain self-loop (infinite recursion), chainOp set
without chainNextId (dangling chain), chainNextId set without
chainOp (dead pointer warning), and unresolved chainNextId
references.
