v0.8.0

• Add opt-in teleoperation demonstration collection: native acquisition sinks,
  bounded asynchronous recording, operator episode review, provenance/quality,
  read-only crash inspection, causal alignment and optional LeRobot export.
  Include integrated camera previews and offline simulated operator rehearsal.
  Complete operator-run dual-arm collection trials with three RGB cameras and
  two tactile pads, preserving native timelines and explicit episode acceptance.
• Add operator-triggered synchronized follower return to zero (J1–J7, peak
  commanded speed 5 degrees/s, gripper held), followed by relative takeover from
  the leader's current pose. No precise leader alignment or firmware-zero writes.
  Exclude recording during return/hold and retain stop/disconnect disable cleanup.
• Use official Enactic OpenArm v2 J1–J7 PD gains in shared follower hold/tracking;
  retain existing gripper gains. Operator trials validate the workflow; tracking
  error remains motion-dependent, not a full-workspace accuracy guarantee.
• Move diagnostic report writing off the CAN control loop and record dispatched
  gains, commands, pre-command observations and post-command feedback separately.
