 * Attempt to repair known-safe frontmatter defects.

 * Handled defects (pre-0.3.1 schema drift, observed on 5 auto-extracted
 * solutions from 2026-04-10):
 *   - `extractedBy` missing → add `extractedBy: auto`
 *   - `evidence` block missing → add `DEFAULT_EVIDENCE`
 *
 * All other validation errors (bad scope, non-numeric confidence, etc.)
 * are surfaced in `remaining_errors` and the file is left untouched —
 * those require human judgement, not a mechanical default.
 *
 * `dryRun: true` (default) reports what would change without writing.
