feat(pipeline): add WSMC (Wowee Spell Mechanic) catalog

54th open format — replaces SpellMechanic.dbc plus the
AzerothCore-style diminishing-returns (DR) tables. Defines
crowd-control mechanic categories that spells reference:
Stun, Silence, Polymorph, Sleep, Fear, Root, Snare, Slow,
Knockback, etc. Each mechanic carries gameplay metadata
(breaks-on-damage, can-be-dispelled, default duration, max
stacks) plus DR category and dispel type.

8 DR categories (DRNone / DRStun / DRDisorient / DRSilence
/ DRRoot / DRPolymorph / DRControlled / DRMisc) — the
runtime uses these to gate repeated CC on the same target.
7 dispel types (DispelNone / Magic / Curse / Disease /
Poison / Enrage / Stealth) bind which dispel spells can
remove the mechanic. conflictsMask is a bitmask of OTHER
mechanic IDs — only one mechanic from a conflict-group can
apply to a target simultaneously.

Cross-references with prior formats — mechanicId is
referenced by WSPL.spellId entries that apply this CC; this
catalog is referenced from spell tags rather than referencing
out.

CLI: --gen-smc (3 baseline Stun/Silence/Snare), --gen-smc-
hard (5 hard-CC: Stun/Polymorph/Sleep/Fear/Knockback with
conflictsMask wiring), --gen-smc-roots (4 movement-impair:
Root/Snare/Slow stacking 5x/GroundPin breaks-on-damage),
--info-wsmc, --validate-wsmc with --json variants. Validator
catches id+name required, DR category 0..7, dispel type
0..6, maxStacks=0 (mechanic could never apply),
canBeDispelled+DispelNone inconsistency, and self-conflict
bit set in conflictsMask (mechanic blocking itself).

Format graph: 53 → 54 binary formats. CLI flag count: 784
→ 789.
