v0.5.0

Added

• Jump between annotations: N / P (from either pane) move the cursor to the
  first line of the next / previous annotated span, crossing into the nearest
  adjacent commit with an anchored annotation once the current diff is
  exhausted.
• Reload the review state without restarting: R re-reads revisions, the diff,
  and the annotation log from disk, reflecting work an agent did while margin
  stayed open. The same reload also runs automatically as soon as the annotation
  log changes on disk.

Fixed

• The selected commit/file/annotation in the top band no longer keeps the
  cursor background tint once focus moves to the diff; an unfocused band now
  marks its selection with bold alone, matching the diff cursor.

Changed

• The timeline popup (t) now aligns under the annotation's text and opens
  directly above or below the annotated line(s) instead of covering them. Events
  read newest-first as one connected thread (subdued bullets joined by a
  continuing bar), long replies word-wrap with the bar carried down every line,
  and the border is muted.
• The TUI input loop is now async and fully event-driven (crossterm
  event-stream + notify on a futures-lite executor): it reacts to key
  input and filesystem changes via wakers instead of polling on a timer, so it
  no longer wakes periodically while idle.
