Maintenance release.

• Addressed reviewer feedback on 1.0.13: the runtime message listener is no longer asynchronous.

Compatible with Thunderbird 128 and later.

Initial public release.

• Scan all accounts and folders for subscriptions (List-Unsubscribe headers + embedded unsubscribe links in 13 languages)
• Scan scope controls: choose which accounts and folders are scanned, and filter From or To addresses and whole domains
• One-click (RFC 8058), email, and browser unsubscribe methods, with retry via any detected method
• Cleanup actions to delete, move, or mark a sender's messages as Junk
• Keep a subscription while deleting or moving its existing emails
• Default unsubscribe cleanup setting to preselect Leave, Move, or Delete
• Alias-aware grouping by sender and receiving address
• Hardened against malicious senders: suspicious unsubscribe links are blocked before opening, one-click endpoints must use public HTTPS, email content is never rendered as HTML, and a warning appears before unsubscribing from senders without the standard unsubscribe header
• Safe defaults: existing emails are kept on unsubscribe unless you choose otherwise
• Optional dry-run mode to preview every action before it runs
• Keep / dismiss / review-again workflow with a stats dashboard
• Background Activity stack for unsubscribe and cleanup jobs, with progress, details, cancellation, and manual dismiss
• Live message-level progress with pause and cancellation for scans and cleanup operations

Compatible with Thunderbird 128 and later.
