GitHub Actions on push/PR (macOS runner): checks out the vendored SDK
submodule (full history so its pinned fork-branch commit is reachable),
builds the frontend (tauri-build needs ui/dist), then runs
`cargo fmt --check`, clippy (advisory for now), and
`cargo test --workspace`. Caches cargo to keep runs reasonable.
Also point .gitmodules at `tutabridge-integration` (the branch the
submodule commit actually lives on).
- Add tuta-repo as git submodule pointing to spartanz51/tutanota
branch feat/rust-sdk-blob-read (pending upstream PR)
- Remove inline load_mail_details_blob hack, call through
mail_facade().load_mail_details_blob() instead
- Remove /tuta-repo from .gitignore since it's now a submodule
