• Introduced golem-llm-bedrock component with necessary dependencies and configurations.
• Updated Cargo.toml and Makefile.toml to include new build tasks for Bedrock.
• Enhanced README.md to document the new Bedrock LLM implementation.
• Implemented client and conversion logic for interacting with AWS Bedrock APIs.
• Added streaming support and message conversion for Bedrock models.
• Updated test configurations to include Bedrock component builds.
