Do not merge: submodule commit exists only on an unmerged feature branch.

The new commit hash 4defa4b927a0915e6417ec3662bb035647e0ab0a is not reachable from the rain.metadata repository's main branches. This commit exists only on the feature branch for PR rainlanguage/rain.metadata#84, which is currently OPEN and not merged. Pinning the submodule to a commit on an unmerged branch creates a broken dependency state.

Before updating the submodule:

1. Ensure rain.metadata#84 is merged to a stable branch (main/master)
2. Then update lib/rain.metadata to point to that finalized commit
