- shared eco.widgets.live_values: writes on a background thread with a
status dot (and working Stop during a move), reads off the GUI/kernel
thread, monitored items subscribed (trusted only once an event arrives,
demoted if a poll sees an unannounced change), tweak step from the IOC's
TWV for motor/SmarAct records.
- assembly_browser Set no longer falls back to mvr (a relative move with
an absolute value); runs off the kernel thread.
- fix process aborts: IOC finder worker destroyed while running, simple
gadget polling after close; tweak panel message timer guarded.
