0.57.7: Routing Cleanup and Recipient Recovery

• Recipient recovery: A forwarded input journaled for a follower whose Thread was re-created no longer retries forever against the old Thread. After the leader refuses that reply, the input re-runs once against the follower's current Thread; a second refusal or any other failure keeps the durable retry state, and nothing is dropped.
• Transit cleanup: Cancel remains journal-first when its Telegram view is unavailable. A parsed exact-target deletion/absence response now finishes temporary-tab cleanup instead of retaining a stuck issued entry. Closed, denied, foreign, malformed and forged responses stay protected without retry. Native regressions also prove waiting-tab protection across cold reads and unavailable state, and refusal to cancel custody already handed to a queue.
• Routing expiry: Expired inputs now receive an explicit undelivered/unconfirmed notice even when the chooser message is gone. Cold expiry uses the journal's saved chooser; a disappearing or unavailable view falls back only to the leader's current owned Thread, never All. Selected/issued work is not falsely called undelivered, accepted recipient work continues, and stale authority or failed notices cannot replay input or authorize deletion.
• Manual cleanup: Leader Settings can review and separately confirm deletion of inactive Telegram tabs and their messages, including bindings without a letter. Pi history/project files and replacement letter holders stay untouched. Exact review, live-work protection, profile/session/leader fences and one-shot permits are rechecked; changed/protected tabs are skipped, unknown deletion never repeats and interrupted commits remain recoverable. Review and Back delete nothing.
• Thread titles: Reassigning a letter immediately attempts to retitle the displaced Thread with its retained name, preserving manual titles and all history/work. Slotless bindings participate in later display reconciliation without acquiring routing ownership. Failed or unacknowledged edits keep prior title evidence, record a diagnostic and never undo reuse or delete the Thread.
