feat(pipeline): add WTAL (Wowee Talent catalog) format

Novel open replacement for Blizzard's TalentTab.dbc +
Talent.dbc + the AzerothCore-style talent_progression SQL
tables. The 25th open format added to the editor.

Defines class talent specialization trees: per-class set
of named tabs (Arms / Fury / Protection for warrior, Fire
/ Frost / Arcane for mage), each with talents arranged in
a row/column grid, each talent having up to 5 ranks and
an optional prerequisite chain.

Cross-references with previously-added formats:
  WTAL.talent.prereqTalentId -> WTAL.talent.talentId
                                 (intra-format chain)
  WTAL.talent.rankSpellIds[] -> WSPL.entry.spellId
                                 (spell granted at each rank)

Format:
  • magic "WTAL", version 1, little-endian
  • per tree: treeId / name / iconPath / requiredClassMask /
    talents[] (row, col, maxRank, prereqTalentId+rank,
    rankSpellIds[5] zero-padded for unused ranks)

Enums:
  • ClassMask: bit positions match canonical CharClasses.dbc
    classIds — Warrior / Paladin / Hunter / Rogue / Priest /
    DK / Shaman / Mage / Warlock / Druid

API: WoweeTalentLoader::save / load / exists +
WoweeTalent::findTree / findTalent (global lookup across
all trees in the catalog).

Three preset emitters showcase tree shapes:
  • makeStarter — 1 small tree (3-talent vertical chain)
  • makeWarrior — 3 trees (Arms 4 / Fury 4 / Protection 3)
                   with WSPL cross-refs at capstones
                   (Mortal Strike -> WSPL 12294, Battle Shout
                   -> WSPL 6673, Thunder Clap -> WSPL 6343)
  • makeMage    — 3 trees (Arcane / Fire / Frost) with
                   capstones referencing Frostbolt 116 /
                   Fireball 133 / Blink 1953 from WSPL

CLI added (5 flags, 571 documented total now):
  --gen-talents / --gen-talents-warrior / --gen-talents-mage
  --info-wtal / --validate-wtal

Validator catches: tree+talent ids=0 or duplicates, empty
tree name, requiredClassMask=0 (every class would see this
tree — usually a typo), maxRank not in 1..5, talent listing
itself as prerequisite, prereqTalentId pointing at a
talent that doesn't exist in this catalog (intra-format
cross-reference resolution), prereqRank=0 or > the prereq
talent's maxRank (catches off-by-one references), gaps in
rankSpellIds progression (rank N has spell but rank N-1
doesn't — usually a typo).

The validator caught a real authoring bug in the makeMage /
makeWarrior presets during smoke testing — initial check
was comparing prereqRank against the WRONG talent's maxRank
(this talent's rather than the prereq's). Fixed in the same
commit by hoisting the check into the cross-reference
resolution pass where the prereq talent is in hand.
