cckbc/dsh-session-recycle-bin

Session recycle bin for DeepSeek Harness: deleting a session from its row menu (or in bulk from the sidebar header) moves it into a recycle bin kept for 15 days by default — 7, 15 or 30 in settings — and expired entries are purged automatically. The bin table shows the days left for each entry, restores it to its original workspace, and can delete an entry for good, one at a time or all at once.
