๐ Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a ๐ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

- Same issue as above:
catch (e: Exception)will silently swallow unexpected runtime errors while the comment implies only access issues are ignored. Narrow the catch clauses to the expected I/O/security exceptions (andDirectoryIteratorException), or rethrow unknown ones.

// Ignore access denied exceptions
