Subject: [PATCH] fix: URL encode model names to support inference profiles

AWS Bedrock inference profiles contain special characters (colons and
slashes) in their ARNs that must be URL encoded when used in the API
endpoint path.

Example inference profile:
arn:aws:bedrock:us-east-1:123456789012:application-inference-profile/abc123def456

This change adds rawurlencode() to the model name before constructing
the base URL, ensuring inference profiles work correctly.
