feat(pipeline): WMOD addon manifest catalog (125th open format)

Novel replacement for vanilla per-addon TOC (.toc) text files
scattered across Interface/AddOns/. Each WMOD entry binds one
addon to display metadata (name / description / version / author),
client-build gate (minClientBuild), persistence + lazy-load
flags (requiresSavedVariables / loadOnDemand), and required +
optional dependency lists.

Three presets:
  --gen-mod        4 vanilla-era addons (Recount standalone +
                   Atlas standalone + Auctioneer optional-dep
                   on Atlas + Questie standalone)
  --gen-mod-ui     3 UI-replacement chain (Bartender4 root ->
                   ElvUI required-dep on Bartender4 -> SuperOrders
                   required-dep on ElvUI). Exercises the chained
                   required-dep resolution path.
  --gen-mod-util   3 standalone utility addons (XPerl, Decursive,
                   GearVendor loadOnDemand) — empty-deps baseline.

Validator catches: id+name+version required, duplicate addonIds,
duplicate addon names (load-order ambiguity), self-dependency
(load deadlock), missing required-dep addonId, full DFS cycle
detection on required deps (deadlock at load — extracts the
back-edge path so the user can see the loop). Warns on optional
self-dep (no effect, prune) and on minClientBuild < 4500
(below vanilla floor — likely typo).

Format count 124 -> 125. CLI flag count 1319 -> 1326.
