What
When a session starts, the control channel now sends a set_max_thinking_tokens request carrying a maximum thinking token count, a thinking display setting, or both, if the caller supplied them.
Details
Sent only when thinking.maxThinkingTokens or thinking.display is provided; otherwise nothing extra goes out.
Sits next to the existing set-mode request, which switched from generating a random UUID to a shared id helper.
Evidence
subtype: "set_max_thinking_tokens"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
