fix(completion): CompleteDone reason="discard" when candidate text remains #38169

Browse Source 
Problem: CompleteDone fires with reason="discard" even when the candidate
text was inserted and left in the buffer, because reason was determined
solely by the terminating keycode (Ctrl-Y).

Solution: Check compl_used_match to detect whether inserted
text remains in the buffer, and set reason="accept" accordingly.
