feat(pipeline): add WSND (Wowee Sound Catalog) format

Novel open replacement for Blizzard's SoundEntries.dbc +
SoundEntriesAdvanced.dbc. The 10th open format added to the
editor — covers the audio-metadata gap (the previous 9 cover
geometry, terrain, atmosphere, and world manifests, but no
sound metadata).

Format:
  • magic "WSND", version 1, little-endian
  • catalogName + entry count
  • per entry: soundId / kind / flags / volume /
    minDistance / maxDistance / filePath / label

Kind enum (7 categories):
  sfx, music, ambient, ui, voice, spell, combat

Flags packed (3 bits used, rest reserved):
  loop (0x01), 3d (0x02), stream (0x04)

API: WoweeSoundLoader::save / load / exists; presets
makeStarter (one entry per kind), makeAmbient (wilderness
loops + footsteps), makeTavern (fire + crowd + drink + door
+ lute).

CLI added (5 flags, 465 documented total now):
  --gen-sound-catalog <base> [name]
  --gen-sound-catalog-ambient <base> [name]
  --gen-sound-catalog-tavern <base> [name]
  --info-wsnd <base> [--json]
  --validate-wsnd <base> [--json]

Validator catches: out-of-range kind, NaN/inf volume or
distances, 3D sounds with bad min/max, duplicate sound IDs,
empty filePaths.

All 3 presets verified: save / load / validate clean
on first run. Variable-length string fields use length-
prefixed encoding with a 1 MiB sanity cap on read to
prevent corrupted-file allocation blowups.
