fix: prevent log.writeSummary from overwriting reportProgress content (#87)

* fix: prevent log.writeSummary from overwriting reportProgress content

The run summary was showing logs instead of the final reportProgress content
because log.writeSummary() was called after reportProgress. Now
log.writeSummary() checks if the summary was already overwritten by
reportProgress and skips if so.

Fixes #86

* refactor: replace dynamic import with static import in cli.ts

Replace unnecessary dynamic import of wasSummaryOverwritten with
static import. No circular dependency exists since comment.ts doesn't
import from cli.ts.

* Fix run summary writing
