teknium1 7653424356 fix(anthropic): Opus 5.5 keeps thinking on, Sonnet 5.5 turns it off with between_tools
Reasoning off sent thinking: {type: disabled} to both. Anthropic documents
that Opus 5.5 always thinks and 400s on disabled, and that Sonnet 5.5 400s
on disabled with a message pointing at between_tools, its lowest setting.
Every /reasoning none turn and every auxiliary call that disables thinking
(titles, compression) failed on these models.

Opus 5.5 joins Fable in keeping the omission; Sonnet 5.5 sends
between_tools. Sonnet 5 still takes the plain disable.
