Repo panel renders on top of repo content again (regression of #4) #17

The Repository / OSSF Scorecard panel is injected full-width above the repo header instead of the About sidebar.

Cause: findRepoSidebar falls back to main, which always exists, so waitFor(findRepoSidebar, …) resolves immediately, before React renders the About pane ([data-component="SplitPageLayout.Pane"]). The CodeViewSidebar-module__borderGrid selector also no longer matches (class is now hashed, e.g. CodeViewSidebar-module_6TmlqG_borderGrid).

Fix: move the content fallbacks out of findRepoSidebar and only use them after the wait times out; make the borderGrid selector hash-agnostic.
