PR Summary

Low Risk
Routine automated documentation/submodule sync with no application logic changes visible in the diff.

Overview
Automated nightly docs refresh from the scheduled update-nightly workflow (pnpm docs:update:nightly --from-workflow).

The supplied diff is empty (no file hunks), so this PR may be a no-op run, or changes may be limited to git submodule pointer updates under docs/nightly/ that are not shown in the text diff. When updates do land, they typically bump those submodules to newer upstream nightly revisions via updateSubmodules.
