Overview

Progress observer that flushes the canonical report to disk periodically during a run, so a crash on a long run keeps partial results and the report grows visibly mid-run instead of appearing only at the end (Gate 5).

Each flush serialises only the mutants completed since the previous flush and folds them into the on-disk JSON report. When HTML reporting is active, the self-contained HTML report is regenerated from that merged JSON schema. Reuses Result#to_stryker_schema and CanonicalReportWriter.

On a full (authoritative) run the first flush replaces the report — wiping entries left by earlier runs, including deleted files — and later flushes merge their batch in. On a scoped/partial run every flush merges, matching the end-of-run reporter's behaviour.
