fix(coding-agent-find-tool): corrected find glob ordering by mtime

- Propagated `combinedSignal` into `doGlob` so cancellation is honored during glob execution.
- Skipped fallback `doGlob(false)` when `timeoutSignal` was aborted to avoid redundant work.
- Sorted `result.matches` by descending `mtime` in JS to return the most recent hits first.
