Deploy an agent

Replace .unwrap() and panic!() calls with proper error handling to prevent crashes and improve robustness. When encountering potential failures, choose one of three approaches:

1. Propagate the error to the caller using Result types
2. Log and continue with graceful degradation
3. Use .expect() with clear, actionable messages if crashing is truly intended

Examples:

Instead of:

let result = receiver.recv().unwrap().unwrap();

Use propagation:

fn get_result(&self) -> Result<SomeType, Error> {
    let result = receiver.recv().map_err(|e| Error::IpcFailure)?
        .map_err(|e| Error::OperationFailed)?;
    Ok(result)
}

Instead of:

devtools_chan.send(msg).unwrap();

Use logging:

if let Err(e) = devtools_chan.send(msg) {
    log::error!("DevTools send failed: {e}");
}

Instead of:

let components = string.split('x').collect::<Vec<_>>();
Ok(Some(Size2D::new(components[0], components[1])))

Use graceful handling:

let (width, height) = string.split_once('x')
    .ok_or(ParseResolutionError::InvalidFormat)?;

This approach prevents unexpected crashes, especially in content processes, and provides better debugging information when failures occur.
