Extract registry types into workspace package (#5840)

## Summary

Extracts ComfyUI registry types into a dedicated workspace package for
better modularity.

## Changes

- **What**: Created `@comfyorg/registry-types` package to house
generated type definitions
- **Breaking**: None - maintains backward compatibility through
re-exports at original path
- **Dependencies**: Added `@comfyorg/registry-types` as workspace
dependency

## Review Focus

Is this the right granularity for package extraction, or should registry
types be part of a larger shared package?

PR split into two tiny diffs:
- [Part
one](f8d3d2fa01)
- [Part
two](f8d3d2fa01..c48ca84336)
