Shift+Up and Shift+Down step the effort level, with tips and hints

What

The effort level sets how much thinking Claude puts into a reply, and you normally change it with /effort. There are now keyboard actions to step it up or down.

• Keys: the default chat key map binds shift+up to chat:increaseEffort and shift+down to chat:decreaseEffort. Which builds or conditions fill in these bindings is not shown.
• Cache warning: if a step would miss the prompt cache, a store of recent input that makes replies cheaper and faster, an effort confirmation prompt appears first. Stepping up when the next step would be max shows "stops below max · /effort max to set it".
• Tip: a new tip, effort-step-keys, says to press these keys to "raise or lower the effort level for this session". It shows only when both bindings are set as plain keys and a feature check passes.
• Hints: the shortcuts help panel gets a new entry under the same check, and a dimmed "change effort" hint can appear on screen under a condition that was not resolved.
• Status line: the effort status line can now end with "may wait for your next message" instead of "/effort".

Why

You can change effort without typing a command. Watch for the confirmation prompt, since changing effort mid-conversation can cost a cache miss, and for the status line saying the new level may only apply from your next message.
