refactor(physics #145): Slice 1 — rename Frame->CellFrame to avoid DatReaderWriter.Types.Frame collision

Browse source 
The new value type collided with DatReaderWriter.Types.Frame (used in
physics-adjacent code like ShadowShapeBuilder), which the structural fix
(per-file using-aliases across 6 files) would have re-incurred in every
later physics slice. Renamed the TYPE to CellFrame; the Position.Frame
MEMBER keeps retail's name. Restored the 5 alias-only files to their
pre-Slice-1 state; synced spec + plan. Core 1522 passed / 0 failed.
