* fix(hosted_vllm): keep reasoning_content on assistant messages in _transform_messages
vLLM accepts reasoning_content (200 on the wire) and qwen/deepseek/glm
chat templates consume it, so popping it made reasoning models lose
earlier reasoning across tool loops. thinking_blocks is still removed
for vLLM compatibility.

* fix(hosted_vllm): forward replayed reasoning_content only when it is a string
* test(integration): cover hosted_vllm reasoning_content replay across endpoints
* test(integration): require the surviving worker to serve its held requests in the sigkill chaos cell

* fix(router): stream anthropic messages lifecycle frames live when no fallback can take over
The /v1/messages streaming wrapper buffered message_start and
content_block_start until the first content_block_delta and dropped
pings behind buffered frames unconditionally, even for requests no
fallback could ever recover. With adaptive thinking on Bedrock or
Vertex the client saw no bytes for the whole thinking pass and hit
read timeouts.
Buffering now applies only while a fallback can still take over
(generic or refusal chain resolving), and a ping is always forwarded
live since it carries no lifecycle and keeps the connection alive.
