* feat(strands_decider): call a Strands Decider on an AgentCore runtime ARN
A strands_decider deployment whose api_base is a bedrock-agentcore runtime ARN now
calls InvokeAgentRuntime on that runtime, signed with SigV4 from the deployment's aws_*
params or the default chain, reuses one session per runtime, and maps the runtime's
200 error envelopes to 400, 503, or 500
* ci: run the strands_decider unit tests in the llms job
* fix(strands_decider): take the AgentCore session id from the deployment, never the caller
A caller could pick the runtime session through extra_headers, and every new id starts another microVM. The session id now comes from the deployment's agentcore_runtime_session_id (banned in request bodies) or the ARN default, and caller-supplied host, x-amz-*, and x-amzn-bedrock-agentcore-runtime-* headers are not forwarded
* fix(strands_decider): map runtime error replies only on AgentCore ARN calls
* fix(strands_decider): sign plain decisions calls inline, off the AWS signing executor
* test(strands_decider): cover AgentCore runtime ARN calls in integration wire tests
