Add export subcommand and Unity PoC-1 scaffold (ONDEVICE §4)
Python (ipin_vr/export.py):
- generate_bank(): levels 1–2 enumerated exhaustively (120/720 combos),
level 3 random with dedup; all deduplicated per-level
- run_export(): CLI --per-level / --out / --seed flags per ONDEVICE §4.1
- cli.py routes "export" subcommand before session args (backward-compat)
- 14 new tests: format, dedup for all 3 levels, space caps (L1=120, L2=720),
seed determinism, file output
Unity scaffold (ondevice/Scripts/):
- CommandBank.cs: loads commands.json from StreamingAssets (WebRequest on Android)
- TtsManager.cs: sherpa-onnx integration with [SHERPA] stubs, StreamingAssets→
persistentDataPath copy, defensive Speak() with onDone callback
- SessionController.cs: passthrough flow §6, level switching, busy guard on Next
- ondevice/README.md: full manual Editor steps §5 (Unity setup, Meta XR SDK,
sherpa-onnx install, scene wiring, font, build, metrics)
pytest: 37/37 passed
