feat(pipeline): add WMS (Wowee Map / Area) catalog format

Novel open replacement for Blizzard's Map.dbc + AreaTable.dbc
+ the AzerothCore-style world_zone SQL tables. The 26th open
format added to the editor.

Defines two related kinds of locator in one catalog:
  • Maps  — top-level worlds (continents / instances / raids /
            battlegrounds / arenas) with a friendly name,
            type, expansion tag, and player-count cap.
  • Areas — sub-zones within maps with friendly names, parent-
            area chain, recommended level range, faction-
            territory marker (alliance / horde / contested /
            both), exploration XP, and an ambient-sound
            cross-reference into WSND.

The runtime uses Areas for minimap labels, location strings
under the player frame, "Discover Sub-zone" XP gains, and
ambient-music selection on zone entry.

Cross-references with previously-added formats:
  WMS.area.ambienceSoundId    -> WSND.entry.soundId
  WMS.area.parentAreaId       -> WMS.area.areaId (intra-format
                                   sub-zone hierarchy)
  WSPN entries are tied to WMS.area boundaries by
  world position (no direct ID — the runtime resolves
  position -> area at lookup time)

Format:
  • magic "WMSX", version 1, little-endian
  • maps[] (each): mapId / name / shortName / mapType /
    expansionId / maxPlayers
  • areas[] (each): areaId / mapId / parentAreaId / name /
    minLevel..maxLevel / factionGroup / explorationXP /
    ambienceSoundId

Enums:
  • MapType (5):     Continent / Instance / Raid / Battleground / Arena
  • ExpansionId (5): Classic / Tbc / Wotlk / Cata / Mop
  • FactionGroup:    Both / Alliance / Horde / Contested
                      (PvP-flagging zone)

API: WoweeMapsLoader::save / load / exists +
WoweeMaps::findMap / findArea.

Three preset emitters showcase the catalog shape:
  • makeStarter — 1 continent + 3 areas with parent chain
                   (Goldshire is a sub-zone of Elwynn Forest)
  • makeClassic — 2 continents + Deadmines instance + 6
                   areas (Stormwind/Elwynn/Goldshire/Westfall/
                   Duskwood/Teldrassil/Deadmines) with WSND
                   ambient-sound refs
  • makeBgArena — Alterac Valley (40-player BG) + Nagrand
                   Arena (5v5 with maxPlayers=10)

CLI added (5 flags, 578 documented total now):
  --gen-maps / --gen-maps-classic / --gen-maps-bgarena
  --info-wms / --validate-wms

Validator catches: empty map name, unknown mapType / expansion,
BG/Arena with maxPlayers=0 (no participant cap), area ids=0
+ duplicates, empty area name, maxLevel < minLevel, areas
referencing non-existent maps, parentAreaId chains crossing
maps (sub-zones must be on the same world), self-parent.
