fix(kit): add default values for destructured references in addTypeTemplate hooks

hillaryke · hillaryke · commit df8c4f7c649b · 2025-09-15T20:30:59.000+03:00
Fixes issue where nodeReferences, sharedReferences, and references arrays
could be undefined when destructured in prepare:types and nitro:prepare:types
hooks, causing 'Cannot read properties of undefined (reading "push")' errors.

This ensures backward compatibility by providing empty arrays as defaults
when the hook payload doesn't contain these properties.
