gitwink v0.7.0

Added

• Commit search, with a "warp" to context — press / (or Ctrl+F), or
  click the new ⌕ button in the header. The timeline itself becomes the
  result list: words match the commit message (full body), author, and repo
  name, all words must match, and a 4+ character hex term matches hashes by
  prefix. The repo scope is respected; the time window and author filters
  are bypassed while searching (shown dimmed) — the commit you're hunting
  must never hide behind "30d". Press Enter (or the row's ↗) to warp: you
  land in that commit's repo history with the branch filter reset, the
  author filter cleared, and the time window widened just enough to cover
  it — the commit arrives centered, selected, with a highlight pulse. Esc
  steps back: first to the results, then to the view you started from.
• Empty states offer "Search commits" — staring at "no commits match" while
  hunting for one is exactly the moment to learn search exists.

Fixed

• The single-repo graph no longer shatters under an author filter.
  Filtering by author used to leak one graph lane per merge — dots
  staircasing rightward over a bundle of full-height vertical lines, on
  merge-heavy repos within one screenful. Hidden commits are now bridged:
  parent links re-route to the nearest visible ancestor and draw dashed
  ("history elided here"), so the graph stays one coherent set of lanes.

Search covers the scanned commit cache; exact lookup of arbitrary old SHAs
(and warping beyond the loaded window) is planned as the next step.
