SMBC grows levels — the area data and its resolver

The levels exist now. All 68 object streams — 34 enemy layouts and 34 level layouts covering the eight worlds, the bonus rooms, the cloud areas, and the warp zones — are extracted from the disassembly into data/areadata, with the original's low/high address tables collapsed into plain pointer tables. Every stream was verified byte-for-byte against the donor ROM image: each one's full byte sequence appears verbatim in the PRG. One quirk survived the translation honestly: E_GroundArea9 shares its terminator with E_GroundArea10 in the original's memory, so the C arrays each carry their own terminator, which the decoder reads identically.

GetAreaDataAddrs came with them: the area pointer's top two bits select the table base (after the rotation GetAreaType performs), the low five offset into it, and the level header's two bytes unpack into everything the parser reads — scenery, entrance control, timer setting, terrain, and style, with style three becoming the cloud override. The zero-page stream pointers become real C pointers, the same shape the PPU's chr already takes.

Tested through four concrete areas: 1-1's ground layout, 3-3's background colour control, the day cloud area's override, and 8-4's castle. Next: ProcessAreaData itself, the object decoder that walks these streams.
