Ported from the Android edition and completed for the Python relays
(the Android repo only implemented the phone side in Kotlin):
- models.py / mcp_tools.py: optional feature_index on every output and
pattern tool, passed through to the phone relay.
- relay_client.py: routes targeted writes through buttplug-py's
per-feature API (device.features[i].run_output) and validates the
index up front so a bad one fails the ack with the valid indices
listed, instead of dying silently inside a pattern task.
- termux_relay_v3.py: ScalarCmd entries filtered to the requested
actuator index, same fallback semantics as the Android relay engine.
Lets Claude drive e.g. a Dolce's internal and external motors
independently (feature_index 0 / 1) instead of always both together.
