perf: reduce streaming render cost and refresh activity page on demand

- Segment streaming Markdown so completed blocks are reused and only the growing tail is re-parsed; fall back to whole-document parsing for document-wide constructs - Memoize conversation sidebar rows and cache per-conversation derived activity, ordering and pending approvals - Activity page loads on entry, refreshes every 15 s while visible, and has a single header refresh button - Include pending settings, model download source, device sharing and knowledge gateway changes in the working tree - Add Electron streaming input benchmark and regression tests
