feat(editor): add WCRE (Creature Resistance & Immunity) — 106th open format

Novel replacement for the per-creature resistance columns
that vanilla WoW buried inside creature_template
(resistance1..6 fields) plus the SpellSchoolMask immunity
and mechanic_immune_mask columns. Each entry is one
creature's full defensive profile: 6 magic-school resist
values (int16, with 32767 as the full-immunity sentinel),
a physical-resistance percentage (0..75 game-engine cap),
plus three immunity bitmasks (CC kinds, spell mechanics,
magic schools).

The CC-immunity mask uses 14 named bits: ImmuneRoot /
Snare / Stun / Fear / Sleep / Silence / Charm / Disarm /
Polymorph / Banish / Knockback / Interrupt / Taunt /
Bleed. The info display renders the mask as a "+"-joined
token list ("root+stun+fear") for readability; "all" for
0xFFFF (typical raid-boss CC profile) and "none" for 0.

Three preset emitters: makeRaidBosses (5 canonical raid
bosses with iconic single-school immunities — Ragnaros
fire / Vael 50%-all / Hakkar arcane / Kel'Thuzad shadow
/ Onyxia fire+frost partial), makeElites (5 mid-tier
elites with single-school resists), makeImmunities (4
selective CC-immunity test cases — root-immune treant,
stun-immune worg, silence-immune acolyte, fear+charm+
poly-immune undead).

Validator's most novel check is creatureEntry uniqueness
— multiple WCRE entries binding the same creature would
make the damage-calc lookup ambiguous (which profile
applies?). Also catches negative resists < -100 (extreme
>2x damage taken), physicalResistPct > 75 (clamped at
runtime to game-engine armor cap), and reserved bits in
schoolImmunityMask (only bits 0-5 are meaningful).

Format count 105 -> 106. CLI flag count 1162 -> 1167.
