feat(pipeline): add WSUF (Wowee Item Random Suffix) catalog

64th open format — replaces ItemRandomProperties.dbc +
ItemRandomSuffix.dbc plus the AzerothCore-style suffix-roll
tables. Defines random "of the X" suffixes that roll on
green and blue items at world drop ("Sturdy Cloth Cap of
the Bear" = base item + STR + STA suffix).

5 suffix categories (Generic / Elemental / Defensive /
PvPSuffix / Crafted), per-suffix item-quality bracket gating
(only blue+ items can roll PvPSuffix), restricted-slot mask
that limits which equipment slots a suffix can apply to (15
slot bits matching WCEQ slot enum), and up to 5 stat bonus
slots per suffix matching WoW canonical max.

statValuePoints isn't an absolute number — it's a scaling
base that the runtime multiplies by an item-level
coefficient to compute the final per-item bonus, so "of the
Bear" gives proportionally more strength on a level-60 item
than on a level-20 item.

Cross-references with prior formats — statKind values match
WIT.statType enum (STR=4, AGI=3, INT=5, SPI=6, STA=7) so
item generators roll consistent stats with base items.

CLI: --gen-suf (3 generic stat triads — Bear STR+STA, Eagle
INT+SPI, Tiger STR+AGI), --gen-suf-magical (4 elemental
spell-power suffixes restricted to caster-eligible slots),
--gen-suf-pvp (3 PvPSuffix entries with resilience + offensive
stats, blue+ quality only), --info-wsuf, --validate-wsuf with
--json variants. Validator catches id+name required, category
0..4, quality range valid (0..7 covers heirloom), itemQuality
floor<=ceiling, stat-kind/value pairing (kind=0 with value!=0
is a typo, vice versa), and no-stats warning (suffix renames
item without changing it).

Format graph: 63 → 64 binary formats. CLI flag count: 854
→ 861.
