test: Update tests to handle error-throwing schema loader
Adjust tests to work with the merged changes from main where loadSchema now throws errors instead of silently falling back when custom schema URLs fail to load. - Add network permission checks using Deno.permissions.query - Update tests to use assertRejects for network failures - Make tests conditional based on network permission status - Handle both with-network and without-network scenarios Tests now properly validate that: - Errors are thrown when custom schemas can't be loaded - schemaSource is reported when schemas are successfully loaded - Default schema loading (no custom URL) continues to work 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
