Handle errors in the collect function with a try-catch block.

[bachdumpling]

This PR potentially fix the issue of tmp file not properly cleared after a failed scan, leading to: ENOSPC: no space left on device, mkdir '/tmp/tmp-8-bsc9NMF2bYaq'

Here's a brief summary of the changes:

• Added a try-catch block to the async function to ensure all exceptions are caught and handled appropriately.
• Upon an error, the browser is closed to free up resources. User data directory and output directory are cleared in case of an error to ensure no data remains.
• In the case of an error, the function now returns an object with status 'failed' and a message indicating that the run failed. Finally, it will make sure to clean tmp directories to handle the next scan.
• example.ts also got updated with error logging.
