Purge empty parent folder

[davidnewhall]

• Closes Empty folder left behind #565

After Unpackerr extracts an item and a Starr app imports it, it waits a while before deleting the extracted content. Sometimes the download client moves the downloaded content before this cleanup action in Unpackerr happens. Previously, Unpackerr would delete the extracted content and leave behind the empty download folder.

This changes the behavior to delete the download folder if it's empty.

Pull request overview

This PR updates Unpackerr’s post-import cleanup so that after extracted content is deleted, it also attempts to remove now-empty parent directories (including the original download folder) to avoid leaving empty folders behind (closes #565).

Changes:

• Extend delete requests to optionally define a “purge root” boundary for parent-folder cleanup.
• Update the delete worker to iteratively purge empty parent directories up to a configured root.
• Wire the new purge-root behavior into the Starr import cleanup path.
