Long async operations in apps can freeze eye bridge

[williamsharkey]

Problem

When an app runs long async operations (multiple sequential _exec calls), the eye bridge can timeout or freeze.

Reproduction

The Project Manager app loads projects with multiple git status calls:

for (const dir of dirs) {
  const status = await Studio.github._exec("git -C ~/repos/" + dir + " status --porcelain | wc -l");
  const branch = await Studio.github._exec("git -C ~/repos/" + dir + " branch --show-current");
  // ...
}

With 3+ projects, this creates 6+ sequential HTTP requests, causing eye commands to timeout.

Impact

• Eye bridge becomes unresponsive
• Can't query state or run new commands
• Must wait for async operations to complete or refresh page

Potential Solutions

1. Batch _exec calls - Allow multiple commands in one request
2. Non-blocking apps - Run apps in isolated context that doesn't block bridge
3. Timeout increase - Longer timeout for eye commands
4. Progress indicator - Show when async ops are in progress
