* fix(anthropic): never carry cache_control on translated thinking blocks
The /v1/messages adapter built every thinking and redacted_thinking block with
cache_control=content.get("cache_control", {}), so a block the client never
marked still came out carrying an empty cache_control. anthropic_messages_pt
replays thinking blocks verbatim and first, so that value landed at content[0]
of the outbound assistant message and Anthropic rejected the request with
messages.N.content.0.thinking.cache_control: Extra inputs are not permitted.
Anthropic's schema has no cache_control on either block type, so there is
nothing to gate or translate here, only to stop copying. Every sibling block
type already routes through _add_cache_control_if_applicable; these two were
the only ones setting the key unconditionally.
This is reachable from any caller that round-trips Anthropic messages through
the OpenAI shape, which is why shadow eval saw it on a majority of sampled
Claude Code turns while the same traffic served natively was fine.
* test(anthropic): assert the outbound wire body for redacted thinking blocks
