feat(editor): add WMNL JSON round-trip (--export/--import-wmnl-json)

Browse source 
Plain-shape JSON sidecar — WMNL has no enum fields to
coerce, just positional + textual data: levelIndex
(uint8), minZ/maxZ (floats), texturePath/displayName
(strings). Float-precise round-trip preserved (the
Stormwind/Dalaran/Undercity Z-range boundaries don't
have any rounding artifacts since they were authored
as integer-multiple values like 80.0, 130.0, 200.0).

All 3 presets (Stormwind/Dalaran/Undercity, 3+4+5 = 12
levels total across the city stack) byte-identical
roundtrip OK. CLI flag count 1196 -> 1198.
