v0.13.0

Added

• Track it — site health over time (ADR-016). Two tools turn the one-off audit
  into a trend:
  • eds_audit_snapshot — run the site audit and record its scores (overall +
    per-dimension + counts) as a row in a history sheet in the site's own
    Document Authoring content (default /audit-history.json, kept private /
    unpublished by default — scores stay yours). One row per day (a same-day
    re-run updates it; idempotent when nothing changed). Returns the change since
    the last snapshot (e.g. "89, ▲7 vs 2026-08-09"). dryRun previews the row;
    publish:true makes the sheet live. Requires EDS_DA_TOKEN.
  • eds_audit_trend — read that history and return a self-contained,
    theme-aware HTML trend view: an SVG sparkline of the overall score over time
    plus per-dimension movement since the last snapshot. format:'text' returns a
    short summary instead. Read-only.
  • Health scoring is now shared (src/audit/score.ts computeScores) so the
    report, snapshot, and trend always agree. History stored as an EDS sheet, read
    defensively (same discipline as the redirects sheet). 40 tools total.
