Automatic AWS Credential Initialization for Bedrock

What: When using AWS Bedrock, credentials are now validated and refreshed automatically at startup.

How to use:

# Configure custom AWS auth commands in ~/.claude.json
{
  "awsAuthRefresh": "aws sso login --profile my-profile",
  "awsCredentialExport": "aws configure export-credentials --profile my-profile"
}

# Or skip auto-initialization if not needed
export CLAUDE_CODE_SKIP_BEDROCK_AUTH=1
claude

Details:

• Runs at startup when CLAUDE_CODE_USE_BEDROCK is set and CLAUDE_CODE_SKIP_BEDROCK_AUTH is not set
• First attempts standard AWS SDK authentication via STS GetCallerIdentity
• Falls back to custom awsAuthRefresh or awsCredentialExport commands if needed
• Includes workspace trust checks before executing custom commands
• Provides visual authentication feedback
