docs(parity): mirror 40250 layout for the logic layer; evaluate embedded Python UI
- SKILL.md: logic units port into extension/src/port/<Lib>/<File>, platform
adapters under extension/src/platform; legacy GDScript owners are migration
sources; python layer frozen until the embedding decision
- port_map.py: logic/python/platform layers with per-layer progress, queue
--layer, LEGACY layout check; inventory adds EterBase, EterPythonLib,
ScriptLib, SpeedTreeLib, SphereLib, EterImageLib
- py_embed_spike.py + docs/PYTHON-EMBED-EVAL.md: the 40250 system.py bootstrap
loads 67/74 root modules unchanged under CPython 2.7 with stub natives
