v0.8.1

• Add same-origin collection visualization at /#collection: fresh/stale
  recording status, stream activity and writer queues, plus read-only episode
  inspection, causal camera/tactile/joint playback and acceptance/quality labels.
  A best-effort status publisher stays separate from native acquisition; recording
  controls reuse the existing teleoperation owner.
• Integrate policy visualization into the platform at /#policy: built-in
  simulated sessions, submitted-target/feedback curves, inference latency and
  bounded episode replay, available through the same port in attach-only mode.
• Preserve calibrated absolute J1–J7 manual controls, trajectory/effort checks,
  queued motor reports and the calibration trajectory without encoder-zero writes.
  Integrate these with v0.8.0's official gains and acquisition observer while
  keeping pre-command observations and post-command feedback separate.
• Retain v0.8.0 demonstration collection, synchronized return-to-zero workflow,
  native recording and export; preserve read-only CAN reconnection recovery.
• Validate merged behavior with offline fake-device tests, installed-wheel tests
  and browser simulation/replay. This release adds no new physical-motion trial.
