Respond to review comment: provide issue template for graceful shutdown mechanism

[Copilot]

Review comment requested creating an issue to track adding a graceful shutdown mechanism to the IpcServer::listen method. The current implementation runs an infinite loop with no external control.

Changes

• Responded to comment explaining permission constraints prevent direct issue creation
• Provided complete issue template including:
  • Title and description of the missing graceful shutdown capability
  • Current behavior: loop only exits on channel close or transport error
  • Proposed solutions: cancellation token, shutdown signal channel, or similar interrupt mechanism
• Offered alternative to implement fix directly if preferred

Context

The listen method in src/ipc/src/channel.rs (lines 34-53):

pub async fn listen(&self) -> Result<()> {
    let tx = self.message_tx.clone();
    
    loop {
        match self.transport.recv().await {
            Ok(msg) => {
                if tx.send(msg).is_err() {
                    // Channel closed, exit loop
                    break;
                }
            }
            Err(e) => {
                eprintln!("Transport receive error for {:?}: {}", self.process_type, e);
                // Continue receiving despite errors
            }
        }
    }
    
    Ok(())
}

No code changes in this PR - awaiting direction on whether to track as issue or implement directly.
