Mypy Boto3 Bedrock Agent Runtime Stubs

This library provides PEP 561 type annotations for the `boto3` Bedrock Agent Runtime service. It allows static type checkers like Mypy to validate usage of `boto3.client('bedrock-agent-runtime')`, improving code reliability and developer experience. The current version is 1.42.3 and new versions are released frequently, typically mirroring `boto3` releases and the `mypy-boto3-builder`'s update cadence.
