Bug Fixes

• Follow submodule gitdir files when opening and perform basic validation Modern submodules store a .git file in the worktree whose gitdir: value points at the repository to open. The previous resolver treated every non-directory .git path like an uninitialized submodule and fell back to .git/modules/, which can open the wrong repository after a submodule gitdir is relocated or renamed. That shows up as phantom submodule HEAD changes in gix status.

  Git baseline: Git setup.c::read_gitfile_gently() parses gitdir: files and resolves relative targets against the .git file location; submodule.c::submodule_to_gitdir() consults that gitfile before falling back to the name-derived .git/modules path.

  Update Submodule::git_dir_try_old_form() to validate the submodule name, then follow worktree .git files when present while preserving the old-form directory and uninitialized fallback behavior. Validate present gitdir file targets for direct state/open/status queries so broken submodule checkouts are reported if the gitlink doesn't point to a directory. For status ignore=all, still parse valid gitdir files to keep state accurate, but skip target validation and fall back without error if the gitdir file itself is malformed or unreadable. Derive State::is_old_form directly from whether the worktree .git path is a directory so a divergent modern gitlink is not misclassified as old form.

• Repository::is_dirty() won't fail on unborn repositories
