v5.3.0

What's Changed

• Deleting a torrent now trashes only the files its metadata lists, never the whole folder; magnet deletions leave the output directory untouched.
• Refuse to delete torrent files through symlinked subdirectories.
• Write browser native-host manifests atomically and validate their structure on startup.
• Surface file-trash failures instead of silently ignoring them.
• Center the schedule Date button vertically like the other row buttons.
