feat(runtime): Add AG-UI examples with SSE and WebSocket demos

[rajjainl]

Add tutorial 09-ag-ui-examples demonstrating the AG-UI protocol on AgentCore Runtime with both Cognito/JWT and IAM/SigV4 authentication.

Includes:

• Document co-authoring agent (FastAPI + Strands + ag-ui-strands)
• Cognito notebook with SSE and WebSocket Bearer token demos
• IAM notebook with SSE (SigV4 headers) and WebSocket (pre-signed URL) demos
• Multi-turn interactive document co-authoring demo
• Architecture diagrams for both auth flows and transports
• README with AG-UI event reference and troubleshooting

Latest scan for commit: cb1880b | Updated: 2026-03-24 21:03:21 UTC

Security Scan Results

Scan Metadata

• Project: ASH
• Scan executed: 2026-03-24T21:03:07+00:00
• ASH version: 3.0.0

Summary

Scanner Results

The table below shows findings by scanner, with status based on severity thresholds and dependencies:

Column Explanations:

Severity Levels (S/C/H/M/L/I):

• Suppressed (S): Security findings that have been explicitly suppressed/ignored and don't affect the scanner's pass/fail status
• Critical (C): The most severe security vulnerabilities requiring immediate remediation (e.g., SQL injection, remote code execution)
• High (H): Serious security vulnerabilities that should be addressed promptly (e.g., authentication bypasses, privilege escalation)
• Medium (M): Moderate security risks that should be addressed in normal development cycles (e.g., weak encryption, input validation issues)
• Low (L): Minor security concerns with limited impact (e.g., information disclosure, weak recommendations)
• Info (I): Informational findings for awareness with minimal security risk (e.g., code quality suggestions, best practice recommendations)

Other Columns:

• Time: Duration taken by each scanner to complete its analysis
• Action: Total number of actionable findings at or above the configured severity threshold that require attention

Scanner Results:

• PASSED: Scanner found no security issues at or above the configured severity threshold - code is clean for this scanner
• FAILED: Scanner found security vulnerabilities at or above the threshold that require attention and remediation
• MISSING: Scanner could not run because required dependencies/tools are not installed or available
• SKIPPED: Scanner was intentionally disabled or excluded from this scan
• ERROR: Scanner encountered an execution error and could not complete successfully

Severity Thresholds (Thresh Column):

• CRITICAL: Only Critical severity findings cause scanner to fail
• HIGH: High and Critical severity findings cause scanner to fail
• MEDIUM (MED): Medium, High, and Critical severity findings cause scanner to fail
• LOW: Low, Medium, High, and Critical severity findings cause scanner to fail
• ALL: Any finding of any severity level causes scanner to fail

Threshold Source: Values in parentheses indicate where the threshold is configured:

• (g) = global: Set in the global_settings section of ASH configuration
• (c) = config: Set in the individual scanner configuration section
• (s) = scanner: Default threshold built into the scanner itself

Statistics calculation:

• All statistics are calculated from the final aggregated SARIF report
• Suppressed findings are counted separately and do not contribute to actionable findings
• Scanner status is determined by comparing actionable findings to the threshold

Please take a look

[evandrofranco]

can this block be simplified:

status_response = agentcore_runtime.status()
status = status_response.endpoint['status']
print(f'\n\u2705 Runtime status: {status}')

[evandrofranco]

Can we add a markdown before this, explaining the helper util.py that we are using to create this?
