feat(editor): add WSRG (Spell Range Index) open catalog format

Open replacement for Blizzard's SpellRange.dbc plus the per-spell
range-bucket fields in Spell.dbc. Defines the categorical range
buckets that spells reference instead of carrying their own min/max
yards (every Frostbolt shares one 30y bucket; every Heal shares
one 40y friendly bucket). Each entry carries separate min/max for
hostile vs friendly targets so heals can reach further on allies
than nukes do on enemies, plus an icon color for HUD range
indicators.

Three preset emitters: --gen-srg (3 baseline buckets:
Self/Melee/Spell), --gen-srg-ranged (5 ranged spell buckets:
Short/Medium/Long/VeryLong/Unlimited), --gen-srg-friendly (3
friendly-only buckets where hostile range is 0). --info-wsrg and
--validate-wsrg round out the per-format surface; validation
catches negative ranges, min>max, duplicate ids, out-of-range
rangeKind, and warns on Self+nonzero range or Melee>8y.

Wired through the cross-format table so WSRG appears automatically
in --list-formats, --info-magic, --diff-headers, --summary-dir,
--rename-by-magic, --catalog-grep, --tree-summary-md, and
--touch-tree. Format count 67 -> 68; CLI flag count 885 -> 890.
