feat(editor): add WMSP (Master Server Profile) — 100th open format

Novel replacement for the hardcoded realmlist that the
WoW client receives via SMSG_REALM_LIST during login.
Each entry is one selectable realm: name, network address
(host:port), realm type (Normal/PvP/RP/RPPvP/Test), realm
category (Public/Private/Beta/Dev), expansion gating
(Vanilla 1.12.1 / TBC 2.4.3 / WotLK 3.3.5a / Cata 4.3.4),
population indicator (Low/Medium/High/Full/Locked), char-
acter cap, GM-only flag, timezone hint, and per-realm
version+build numbers.

100th open format — milestone marker for the catalog
ecosystem. WMSP is a TOP-LEVEL bootstrap catalog (read by
the login server before any character is loaded), so it
deliberately has no cross-references to other catalogs;
all other social/world/spell catalogs depend on a player
session that doesn't exist until WMSP has been consulted.

Three preset emitters covering common deployment shapes:
makeSingleRealm (1 default WoweeMain WotLK Public),
makePvPCluster (3 realms — PvE/PvP/RP — sharing one login
address so players pick rule-set without changing servers),
makeMultiExpansion (4 progression realms across all
expansion gates with their canonical build numbers from
the matching client).

Validator catches several real misconfigurations: empty
address (login server cannot route session), realmType
out of {0,1,4,6,8} (the WoW client's RealmType enum is
non-contiguous — 2/3/5/7 are unused values that crash the
picker), characterCap=0 (players can't make characters),
duplicate realm names (picker requires unique display
names), missing port in address.

Format count 99 -> 100. CLI flag count 1119 -> 1124.
