Spindle will sync git repo when new repo is registered Spindle will listen to `sh.tangled.git.refUpdate` event from knot stream and sync its local git repo instead. Spindle's git repo will sparse-checkout only `/.tangled/workflows` directory. Spindle now requires git version >=2.49 for `--revision` flag in `git clone` command.
