PR Summary

Low Risk
Routine documentation submodule refreshes with no application runtime or security logic changes; risk is limited to publishing incorrect or incompatible nightly doc content if pins are wrong.

Overview
This is an automated docs-hub PR from the weekday Update Nightly Versions workflow (pnpm docs:update:nightly --from-workflow). It is meant to refresh the nightly documentation set by bumping the docs/nightly/* git submodules (Sway, fuels-rs/ts, specs, wallet, integration docs, and related sources) when upstream repos have newer releases than what is currently pinned.

No file changes appear in the PR diff supplied for review, so either upstream versions were already current and the run produced no submodule pointer updates, or the diff was not included. Reviewers should confirm whether .gitmodules / submodule commit SHAs actually changed before merging.
