The app held every flow in memory and redid all of its work for each new
one: the sidebar mounted every domain and path node (its tree scrolled
inside a container that never bounded it), every tree row looked up its
atoms by scanning every atom the family had made, and the layout, detail
pane and list rows re-rendered per flow. At 3,000 flows each new one cost
about 90 ms of main thread, more than the traffic left time for.
The app now holds a window of the newest 2,000 flows, applies new ones in
batches, and loads older ones in pages from the database on scrolling to
the top, through a new list_flows RPC that pages in SQL. The database
keeps every flow.
Also adds clear_flows: an RPC, POST /flows/clear on the control API, and
a Clear button in the header that Cmd+K opens, confirming first.
