Adds --export-wgch-json / --import-wgch-json with the established
readEnumField template factoring int+name dual encoding for both
channelKind ("global"/"realmzone"/"faction"/"custom") and accessKind
("publicjoin"/"inviteonly"/"autojoinonzone"/"moderated").
All 3 presets (std-channels / roleplay / admin) byte-identical
binary roundtrip OK including the zoneDefaultMapId=1519 Stormwind
auto-join binding on TradeStormwind. Validators pass on round-
tripped binaries.
CLI flag count 1317 -> 1319.
Novel replacement for vanilla ChatChannels.dbc + the per-server
zone-default chat-join behavior. Each WGCH entry binds one chat
channel to its access policy: PublicJoin, InviteOnly,
AutoJoinOnZone (with zoneDefaultMapId), or Moderated. Entries
also carry channelKind (Global/RealmZone/Faction/Custom),
passwordRequired, levelMin, maxMembers cap, topic-mod-only flag,
and an icon RGBA color.
Three presets:
--gen-gch 4 standard server channels (LookingForGroup,
World, Trade auto-join Stormwind, General)
--gen-gch-rp 4 RP channels (RP_OOC public, RP_IC moderated
200-cap, RP_Forum invite-only 50-cap, RP_Events
password-protected)
--gen-gch-admin 3 moderator-only channels (GMTraffic, AuditLog,
Backstage — all password-gated)
Validator catches: id+name required, channelKind/accessKind
range, duplicate channelIds, duplicate channel names (which
would route /join ambiguously), AutoJoinOnZone with
zoneDefaultMapId=0 (auto-join trigger would never fire). Warns
on dead zoneDefaultMapId set with non-AutoJoin kind.
Format count 123 -> 124. CLI flag count 1290 -> 1317.
