 The setup task runs:
-- `git config core.hooksPath .githooks` - Use version-controlled hooks
-- `git submodule update --init --recursive` - Initialize proto submodule
+- `git config submodule.recurse true` - Auto-update submodules on git commands
+- `git config fetch.recurseSubmodules on-demand` - Auto-fetch submodule changes
+- `git submodule update --init --recursive --remote` - Initialize proto submodule
 - Installs rustfmt, clippy, and nightly toolchain
