Walkthrough

This PR modifies the ACP initialization helper to introduce dedicated temporary directory management. A new private helper function obtains or creates a temporary directory under Electron's userData path, with fallback to process.cwd() if creation fails. The PTY working directory is updated to use this computed temporary directory instead of directly using the process working directory.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Review the new getAcpTempDir() helper logic for proper error handling and fallback behavior
• Verify electron app.getPath() integration and imports
• Confirm PTY session initialization correctly uses the computed workDir across spawn and cwd assignments

Poem

🐰 A cozy warren for ACP to roam,
In userData's safe and sheltered home,
When paths grow tangled or troubles appear,
We hop back to cwd, never fear!
Temp directories tidy, the workspace is clean. 🌰
