Run-from-here now preserves the edited text via an explicit _tgKeepEdit flag
set when the button is pressed, instead of comparing incoming vs last text.
A non-deterministic upstream (random/seeded prompt) regenerates text on every
re-queue, which made the old comparison clobber the edit. Normal toolbar Queue
still shows fresh upstream text.
