The trail survives a page reload

Browse Source 
The self-recorded points now snapshot into localStorage per marker
(raw robot coords, so recalibration does not invalidate them). Restore
is gated: fresher than the linger window, same map, and never into a
run that started after the snapshot ended — the old trail must not
leak into a new cleanup. The smoke simulates the reload by wiping the
runtime map and asserts both the restore and the new-run discard.
