[Bug]: OMP agent status remains stuck at "working" in sidebar after task completes (reproduces on v1.4.206)

Orca version

v1.4.206

Details

Short summary:
When running an OMP (Oh My Pi v18.2.7) agent in Orca on macOS, after a turn finishes (all tool calls completed and final assistant response returned), the sidebar status indicator remains stuck at "working" (yellow spinner) indefinitely instead of settling to idle.

What happened:

• The agent finished executing tools, outputted its final response, and returned control to the user prompt.
• The sidebar entry for the worktree/pane continued to show the yellow spinner and "working" state for >10 minutes.
• Checking ~/Library/Application Support/orca/agent-hooks/last-status.json, the last recorded event was still stuck on:

  "hookEventName": "tool_execution_end",
  "payload": {
    "state": "working"
  }

• It looks like agent_end is either not received, dropped, or fails to transition the sidebar status to done/idle.

How can we reproduce it:

1. Open Orca v1.4.206 on macOS (Apple Silicon).
2. Start an OMP agent (omp/18.2.7) in a workspace pane.
3. Send a prompt that executes multiple tools (e.g., reading/editing files, running build commands).
4. Wait for the agent to complete all tool calls and print its final response.
5. Check the left sidebar: the pane indicator remains in the "working" spinner state even though the agent is idle and waiting for the next user input.

Anything else that might help:

• Observed on v1.4.206 (latest release) on macOS Darwin 27.0.0 (Apple Silicon).
• OMP version: 18.2.7 (installed via bun).
• Related to closed issue [Bug] omp has finished running but the left side is still running #15557 ([Bug] omp has finished running but the left side is still running) which was marked closed by fix(sidebar): keep OMP split-pane status tied to its PTY #21671, but this still reproduces in v1.4.206.
