M5.15: J / K and Select All Keyframes use what the Timeline shows; Graph Editor Auto-Select Graph Type

- J / K (Go to Previous / Next Keyframe) and Ctrl+Alt+A (Select All Keyframes) act on what the
  Timeline shows, as in After Effects: the keys of its revealed properties, layer and comp
  markers and the work area (they used every property of the selected or all layers, revealed
  or not). The commands take `visible: [{layer, prop}]`, which the Timeline fills in; agents
  calling them without it keep the previous behaviour.
- Graph Editor ▸ Auto-Select Graph Type (an "Auto" button, on by default as in After Effects):
  the speed graph when every property shown is spatial (Position, Anchor Point…), else the
  value graph; choosing Value or Speed turns it off.
- Docs: parity, agents.
