feat(pipeline): add WOMX (Wowee World Map index) format

Novel open replacement for Blizzard's WDT (top-level world
definition table). The 9th open format added to the editor.

A WOMX file holds the manifest of which terrain tiles exist
within a world plus a tiny bit of map-level metadata. The
runtime consults it before attempting to load any individual
tile (so missing tiles produce a clean "no data" result
instead of a file-not-found error).

Format:
  • magic "WMPX", version 1, little-endian
  • mapName + worldType (continent/instance/battleground/arena)
  • gridSize 1..128 (typically 64 for continents)
  • defaultLightId / defaultWeatherId (atmosphere preset
    refs, 0 if none — wires into the WOL/WOW pair)
  • packed bitmap, 1 bit per tile, row-major
  • A 64x64 manifest is exactly 512 bytes of bitmap

API: WoweeWorldMapLoader::save / load / exists; presets
makeContinent (64x64 full), makeInstance (4x4 full),
makeArena (1x1 full).

CLI added (5 flags, 456 total now):
  --gen-world-map <base> [name]            (continent)
  --gen-world-map-instance <base> [name]   (4x4)
  --gen-world-map-arena <base> [name]      (1x1)
  --info-womx <base> [--json]
  --validate-womx <base> [--json]

Round-trip verified: continent + instance + arena presets
all save / load / re-validate to byte-identical state with
correct tile counts.
