📝 WalkthroughWalkthroughThis change adds Noitom setup documentation and registers it in the device documentation. It adds a JSON-configured Noitom-to-G1 retargeting pipeline with calibration, torso and wrist orientation handling, arm targets, Pink IK tasks, diagnostics, safety limits, and visualization. It updates action layouts and environment configuration. The mocap plugin now performs bounded event polling, deduplicates avatar updates, and recreates the SDK application when event backlogs exceed limits. Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The Noitom polling change can discard valid motion batches or fail to drain available events, leaving G1 control targets delayed or stale. This is a concrete runtime control-path risk that should be resolved or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

🟡 Changes recommended
The new Noitom SDK event polling treats Error_MoreEvent as a continue, which can spin without draining and can discard already-fetched events, breaking the intended low-latency behavior.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR updates the Noitom mocap plugin to reduce end-to-end motion latency by draining SDK events within bounded per-update budgets, and extends the Noitom→Unitree G1 workflow by adding torso + arm retargeting (plus a declarative IK config) and first-party documentation.
Changes:
- Refactors Noitom SDK polling to drain/aggregate
AvatarUpdatedevents under explicit per-update budgets, with a backlog-reset escape hatch. - Adds G1 torso retargeting and config-driven Pink IK task weighting/limits, plus a checked-in Noitom→G1 IK mapping JSON.
- Adds a new Sphinx doc page for Noitom and wires it into the device docs index and devices listing.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Both poll sites treat Error_MoreEvent and Error_InsufficientBuffer as the same retry signal. The two calls have different contracts: the count query returns a required size, and the buffered read returns data plus a "more remain" status. Handling them identically loses events at one site and can starve the loop at the other.
