PR review (Cursor Bugbot): --continue-dead-time-seconds was applied only on the
adopt branch, so a carry passed on a later same-id re-continue (early-return
path) was ignored. Honor it there too as a monotonic floor: raise dead_time to
the carried value without clobbering time the dir already accumulated. Test
covers the raise and the no-clobber-on-lower-carry cases.
