feat(pipeline): add WSPL (Wowee Spell Catalog) format

Novel open replacement for Blizzard's Spell.dbc +
SpellEffect.dbc + the AzerothCore-style spell_dbc /
spell_proc tables. The 20th open format added to the
editor — completes the canonical-data side of the gameplay
graph.

Each entry holds the metadata side of a spell: name,
description, school, range, mana / cast / cooldown times,
plus a single primary effect. The simplified effect model
(one effectKind + min/max value + misc field) covers the
common cases (damage / heal / buff / debuff / teleport /
summon / dispel) without needing to reproduce the full
multi-effect graph that classic Spell.dbc carries.

Cross-references with previously-added formats:
  WLCK.channel.targetId (kind=Spell)       -> WSPL.entry.spellId
  WQT.objective.targetId (kind=SpellCast)  -> WSPL.entry.spellId
  WCRT.equippedMain (item with on-use)     -> WIT -> WSPL

Format:
  • magic "WSPL", version 1, little-endian
  • per spell: spellId / name / description / iconPath /
    school / targetType / effectKind / cast & cooldown &
    GCD ms / manaCost / range min..max / minLevel /
    maxStacks / durationMs / effectValueMin..Max /
    effectMisc / flags

Enums:
  • School (7):     Physical / Holy / Fire / Nature / Frost /
                     Shadow / Arcane
  • TargetType (6): Self / Single / Cone / AoeFromSelf /
                     Line / Ground
  • EffectKind (7): Damage / Heal / Buff / Debuff / Teleport /
                     Summon / Dispel
  • Flags:          Passive / Hidden / Channeled / Ranged /
                     AreaOfEffect / Triggered / UnitTargetOnly /
                     FriendlyOnly / HostileOnly

API: WoweeSpellLoader::save / load / exists / findById;
presets makeStarter (Strike + Lesser Heal + Power Word:
Fortitude + Hearthstone, one per major effect kind),
makeMage (Frostbolt 116 + Fireball 133 + Arcane Intellect
1459 + Blink 1953, canonical Classic spellIds), makeWarrior
(Heroic Strike 78 + Thunder Clap 6343 + Battle Shout 6673 +
Mortal Strike 12294).

CLI added (5 flags, 535 documented total now):
  --gen-spells / --gen-spells-mage / --gen-spells-warrior
  --info-wspl / --validate-wspl

Validator catches: spellId=0 + duplicates, empty name,
school out of range, effectKind out of range, NaN range,
range/value min>max, FriendlyOnly+HostileOnly conflict
(incoherent), friendly-only with damage/debuff effect
(incoherent), hostile-only with heal/buff effect, buff/debuff
effect with durationMs=0 (instant fade — almost certainly
authoring oversight).

The validator caught a real preset-emitter authoring error
during initial smoke testing — buff spells were setting
effectValueMin without effectValueMax (validator's range
check immediately flagged it), prompting an in-batch fix
to set both fields. This is exactly the catch-the-typo
purpose validators serve.
