panel: readable everywhere, compact/full toggle, change-driven; jump shortcut

- contrast: the summary used attributed-string colors (never vibrant) and
  the subtitles a vibrant system color, so they blended differently over
  light and dark desktops. the panel now uses herdr's mocha colors
  explicitly over a dark tint, identical on any background.
- layout: compact in "when agents are waiting"; in "always" a show all /
  show less toggle switches to the full list (waiting, separator, rest).
- rows are single-line with a trailing ellipsis instead of wrapping.
- render only when the content changes, and log each render, instead of
  rebuilding every view every second.
- --snapshot-panel renders the real panel offscreen over white and black
  after a different first render (stale content would show).
- jump shortcut ctrl+opt+cmd+u (jump_hotkey) runs dingger focus; shortcuts
  are registered by id. an unedited first config file is upgraded.

selftest covers the layout rules and content; e2e step 13 checks the full
list, its separator, and the toggle labels.
