[Bug]: doesn't detect git submodules in the editor #2822

Steps to reproduce

1. Create or open a Git repository that contains at least one Git submodule.
2. Commit and initialize the submodule as usual (e.g. ‎⁠git submodule add ...⁠, ‎⁠git submodule update --init⁠), so the submodule’s files exist on disk.
3. Open this repository in the editor.
4. Try to reference a file from the submodule using the ‎⁠@⁠ search (file/tagging) UI.
5. Type the exact file name or a unique substring from a file that lives inside the submodule.

Expected behavior

Files that live inside initialized Git submodules of the current repository should be indexed and appear in the ‎⁠@⁠ search results, so they can be tagged and referenced like any other file in the repo.

Actual behavior

Files inside Git submodules are not detected at all:

• The submodule directory itself is ignored by the ‎⁠@⁠ search.

• None of the files within the submodule appear in search results, even though they are present on disk and tracked in Git.

• As a result, it is not possible to tag or reference any file that lives inside a Git submodule, which makes working with repos that rely on submodules effectively not usable.
