feat: add structured output support
Add support for Agent SDK structured outputs. New input: json_schema - JSON schema for validated outputs Auto-sets GitHub Action outputs for each field Security: - Reserved output protection (prevents shadowing) - 1MB output size limits enforced - Output key format validation - Objects/arrays >1MB skipped (not truncated to invalid JSON) Tests: - 26 unit tests - 5 integration tests - 480 tests passing Docs: https://docs.claude.com/en/docs/agent-sdk/structured-outputs 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
