Implements ifcurl-5oo. get_checkout() ensures the bare cache is current via fetch_ifc(), then clones it locally to <cache_dir>/checkout/ (no network), and places it at the resolved commit as a detached HEAD — forcing branch creation before any commit. Viewer artefact patterns (*.ifcview, *.rdbview, etc.) are appended to .git/info/exclude so they are locally ignored without touching the repo's own .gitignore. When a newer commit is requested, the checkout fetches from origin (the local bare cache) using the default refspec to avoid git's "refusing to fetch into checked-out branch" error. Unblocks the JSON-RPC connector (ifcurl-242). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
