- Around line 285-293: Update get_object_nodal_positions to transform
environment-relative nodal positions into the embodiment reference frame: obtain
the inverse from _reference_frame_inverse(env_ids) and apply its rotation and
translation to each object’s nodes when available. Keep the existing
environment-relative positions unchanged when no reference-frame inverse is
returned.

sites so `set_result(None)` is called only when the future is not already done
or cancelled. Ensure `env_reset_queue.task_done()` still runs even when
completion is skipped.

Transform nodal positions into the embodiment reference frame.
get_robot_eef_pose returns adapter EEF poses without conversion. For g1_wbc_pink, those poses are controlled in the pelvis frame, while get_object_nodal_positions returns environment-relative nodes. TPS therefore fits one frame and evaluates EEF positions in another. Apply the reference-frame inverse to the nodes.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Do not complete a cancelled reset future.
If a generator is cancelled while it awaits reset completion, asyncio cancels the future. set_result(None) then raises InvalidStateError before env_reset_queue.task_done() runs. Guard completion at both Line 374 and Line 317, but always mark the request done. (docs.python.org)

should we also check whether each subtask's selection strategy can read it? so that we can fail early on incompatible strategies.

makes sense, added a param to declare strategy compatability

instead of sending zeros action holds still for relative-pose control but in absolute-pose envs, that will not hold.
instead, can we use Isaac Lab's uses env_cfg.idle_action when the env defines one. We could check this at launch as well

added, now uses idle_action if configured.

Summary
Add SoftMimicGen deformable data generation
Detailed description
Extend data generation to deformable reference objects. SoftMimicGen selects source demonstrations using nodal state and adapts end-effector trajectories through thin-plate-spline registration.
Stack layer 1/3: Core -> PhysX -> Newton. Environment examples are added by the dependent PRs.
