docs: update structured outputs documentation

Fixed test coverage gap where tests were only parsing JSON manually
without actually invoking the parseAndSetStructuredOutputs function.

Changes:
- Export parseAndSetStructuredOutputs for testing
- Rewrite tests to use spyOn() to mock @actions/core functions
- Add tests that actually call the function and verify:
  - core.setOutput() called with correct JSON string
  - core.info() called with correct field count
  - Error thrown when result exists but structured_output undefined
  - Error thrown when no result message exists
  - Handles special characters in field names (hyphens, dots, @ symbols)
  - Handles arrays and nested objects correctly
  - File errors propagate correctly

All 8 tests now properly test the actual implementation with full
coverage of success and error paths.

+## Network Restrictions
+
+For enhanced security, you can restrict Claude's network access to specific domains only. This feature is particularly useful for:
+
+- Enterprise environments with strict security policies
+- Preventing access to external services
+- Limiting Claude to only your internal APIs and services
+
+When `experimental_allowed_domains` is set, Claude can only access the domains you explicitly list. You'll need to include the appropriate provider domains based on your authentication method.
+
+### Provider-Specific Examples
+
+#### If using Anthropic API or subscription
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # Or: claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
+    experimental_allowed_domains: |
+      .anthropic.com
+```
+
+#### If using AWS Bedrock
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_bedrock: "true"
+    experimental_allowed_domains: |
+      bedrock.*.amazonaws.com
+      bedrock-runtime.*.amazonaws.com
+```
+
+#### If using Google Vertex AI
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_vertex: "true"
+    experimental_allowed_domains: |
+      *.googleapis.com
+      vertexai.googleapis.com
+```
+
+### Common GitHub Domains
+
+In addition to your provider domains, you may need to include GitHub-related domains. For GitHub.com users, common domains include:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    experimental_allowed_domains: |
+      .anthropic.com  # For Anthropic API
+      .github.com
+      .githubusercontent.com
+      ghcr.io
+      .blob.core.windows.net
+```
+
+For GitHub Enterprise users, replace the GitHub.com domains above with your enterprise domains (e.g., `.github.company.com`, `packages.company.com`, etc.).
+
+To determine which domains your workflow needs, you can temporarily run without restrictions and monitor the network requests, or check your GitHub Enterprise configuration for the specific services you use.
