Closes the JSON round-trip gap on the cinematic catalog format
shipped two batches ago. --export-wcms-json emits all 9 scalar
fields plus dual int + name forms for kind and triggerKind so
hand-edits can use either representation. --import-wcms-json
accepts either form, falling back to the int when both are
present. Verified byte-identical round-trip on all three preset
emitters (starter / intros / quests).
41st open format — replaces Movie.dbc / CinematicCamera.dbc /
CinematicSequences.dbc plus the AzerothCore cinematic_camera SQL
table. Defines pre-rendered videos, in-engine camera flythroughs,
text crawls, and still images, each with a media path, duration,
skippable flag, and a polymorphic trigger that fires on quest
events / class first-login / zone entry / dungeon clear /
achievements / level milestones.
Cross-references with prior formats — triggerTargetId resolves
by triggerKind to WQT.questId / WMS.areaId / WMS.mapId /
WCHC.classId / WACH.achievementId, and soundtrackId points at
WSND.soundId.
CLI: --gen-cinematics (3-entry starter), --gen-cinematics-intros
(4 class intros), --gen-cinematics-quests (3 quest-bound
cinematics referencing demo questIds 1/100/102), --info-wcms,
--validate-wcms with --json variants. Validator catches
id=0/duplicates, empty name/mediaPath, kind/trigger out of
range, missing target id for non-Manual/Login/LevelUp triggers,
zero-duration entries, and non-skippable pre-rendered videos.
