* feat: add AWS Bedrock AgentCore browser provider (native Rust)
- Add agentcore provider with SigV4 authentication
- AWS SDK deps are optional behind 'agentcore' feature flag
- Build with: cargo build --features agentcore
- Supports AGENTCORE_REGION, AGENTCORE_PROFILE_ID, AGENTCORE_BROWSER_ID env vars
- Returns session ID and Live View URL in launch response
- Add connect_cdp_with_headers for signed WebSocket connections
* test: add unit tests for AgentCore provider
* refactor: use lightweight manual SigV4 signing instead of AWS SDK
- Replace aws-sigv4/aws-config with manual HMAC-SHA256 signing
- Removes ~60s compile time and significant binary size
- Credentials read from AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY env vars
- Supports AWS_SESSION_TOKEN for temporary credentials
* fix: correct AgentCore API endpoints
- Host: bedrock-agentcore.{region}.amazonaws.com
- Start session: PUT /browsers/{id}/sessions/start
- Stop session: PUT /browsers/{id}/sessions/stop
- Add urlencoding for browser ID in path
- Add AWS_DEFAULT_REGION fallback
* fix: use profileConfiguration.profileIdentifier for AgentCore profile
The AWS Bedrock AgentCore API expects profile configuration in the format:
{
"profileConfiguration": {
"profileIdentifier": "<profile-id>"
}
}
Not the flat "profileId" field that was previously used.
* feat: support AWS credential provider chain via AWS CLI
- Try env vars first (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
- Fall back to 'aws configure export-credentials --format env'
- Honor AWS_PROFILE environment variable
- Works with SSO, IAM roles, credential files, etc.
