port 2D steps 3-4: strict 40250 asset gate with a provenance manifest

tools/asset_manifest.py records path/size/sha256 of pack/Index, every .eix/.epk
and Eternexus/root/*.msm (audit/assets/40250-client.json). The gate script sets
MT_ASSETS_STRICT=1, verifies the manifest, runs the native pack/proto tests and
four Godot tests, and fails on a missing client, a mismatch or a skip.
MT_40250_CLIENT now comes from the environment for the native tests too.
remote_player_test accepts both weighted WAIT variants (wait/wait_1).
PORT-PLAN §5 records the 2D status.
