Protocol upgrade to claude 2.1.204 / SDK 0.3.204, plus a new dashboard card.

🗂 Background tasks in the session dashboard

The plugin now understands the binary's background_tasks_changed signal and shows a Background tasks card (with Stop) listing everything running in the background.

It's a level signal — the binary re-sends the full live set on every membership change — so unlike the edge-derived Subagents list it can never wedge a stale "running" indicator on a missed start/stop bookend. It's deliberately kept uncorrelated with the subagent stream (the SDK leaves their relative ordering unspecified) and resets whenever the CLI process restarts.

🔁 Retry progress for /btw

Progress for long-running side questions (control_request_progress) is now recognised: an API retry is surfaced as a "Retrying (attempt n/m)…" notice instead of being silently dropped.

🧩 Protocol surface

  • Models the new system/background_tasks_changed and system/control_request_progress messages.
  • Triages the new list_models, get_plan and get_workspace_diff control requests — thin-client dialogs the plugin knowingly never sends (its model catalog comes from the initialize reply).
  • ./gradlew checkDrift green at the new baseline.
  • Backward-compatible with older binaries.
