* fix(llmloop): count a grace-round task_done as completion
The grace round after an exhausted budget offers only code_comment and
task_done, and asks the model to call task_done when it has nothing further
to report. That checkpoint was discarded and RunMainTask returned
completed=false, so a file the model had finished was recorded as
incomplete: scan wrote review_item_failed instead of a reusable
review_item_done, and a later resume re-ran it.
Report grace-round completion and return it. Stops that never run a grace
round, and a task_done(FAILED), are unchanged.

* fix(llmloop): warn when a review limit reaches the grace round
A task that spends its tool-request rounds or token budget and then
completes in the grace round reported success with no trace of the
limit, so a zero-finding result could read as clean. Record a
review_limit_reached warning with the stop reason and the round's
verdict, and qualify the zero-finding message in text and JSON output.
Completion, the reusable checkpoint, and budget_exceeded are unchanged.
* fix(llmloop): let failure veto grace-round completion
