shijiewang/dsh-workspace-session-filter

Four filter chips on their own row at the foot of the sidebar: running sessions, sessions waiting for your approval, plan review or answer, sessions with something unread (a turn that finished unseen, or newer activity the panel was not opened on), and sessions updated since local midnight. Each chip counts its matches and opens a popover listing them grouped by workspace, where a row opens the session. The row ends with a DeepSeek service status dot (green operational, yellow partial degradation, red open incident, grey when the feed is unreachable) that subscribes to the status Atom feed once a minute with an ETag conditional request and shows the current finding, the last refresh time and the three newest incidents on hover; clicking it opens status.deepseek.com. A separate panel adds an all-sessions chip, a more menu for the last day, three days, week or thirty days, and a manage mode that searches sessions by title or path, multi-selects them, lists the Markdown digests it has written to the session-digests folder of the DSH data directory in a resizable right-hand column that previews them in place or full screen, writes a Markdown digest and only then moves the session directories to the sessions/.trash folder of that directory; the session you have open cannot be selected.
