Nested .claude/skills/ dirs (previously under server/) are only auto-discovered on-demand once a file under that subdirectory is touched, so /make-widget and /run-server weren't invocable from a fresh session. Root .claude/skills/ is scanned at session start. Fixes setup.sh/start-server.sh's relative cd-depth math (was hardcoded for the old server/.claude/skills/run-server/ depth) to instead resolve the repo root via git and cd into server/ explicitly, and updates SKILL.md/driver.py's path references to match the new layout.
