v1.58.30

[1.58.30] — 2026-05-20

fix(ux): U-10 — Tracker Normalize / Dedup / Merge buttons disabled when data/applications.md is empty. v1.58.3 QA: clicking these buttons on an empty tracker still hit the parent project rewrite endpoints — a no-op the user could not tell was futile. Now public/js/views/tracker.js sets disabled + aria-disabled + a localized tooltip (track.fixEmpty × 8 locales) explaining why ("Add a row to the tracker first — this rewrites data/applications.md and there is nothing to rewrite yet."). When rows exist, the buttons re-enable and show the existing track.fixHint tooltip. 922 → 923 unit. (U-10)
