fix(approve): name --force only where a run is actually suppressed

[pedromvgomes]

A refusal for a review that reached no verdict told the reader to re-run with --force:

$ agtk code-review approve --pr 87
- that review did not reach a verdict, so what it did not find is unknown rather than absent
  agtk code-review run --pr 87 --force

Since v0.12.1 that is the one case a plain run passes: a no-verdict review no longer suppresses the next one. So the flag is an override nothing is stopping them without — and telling a person to force their way past a review that examined nothing is exactly the advice the complete-verdict distinction exists to stop giving.

Not a find-and-replace

gate.go names --force in two remedies and only one is wrong.

unanswered() runs for complete and incomplete markers alike, so its "carries no thread" remedy has to answer the same question rather than be edited alongside. A complete review does suppress a re-run, and there --force is still the only way through.

Both now go through rerunRemedy(number, complete), which names the flag in the one case a plain run declines to pass.

Tests

• TestTheRemedyForANoVerdictReviewDoesNotReachForForce — confirmed to fail against the previous string.
• TestAFindingWithNoThreadOnACompleteReviewStillNeedsForce — pins the case that must keep it, so a later simplification cannot quietly drop --force where it is load-bearing.
