fix: CI workflow path and mcp remove fallback in non-git dirs

- Update `ci.yml` TypeScript test `working-directory` from
  `packages/altimate-code` to `packages/opencode` (post-restructure)
- Fix `mcp remove` fallback logic to avoid accessing filesystem root
  when not in a git repo — only try cross-scope fallback when
  `Instance.worktree` is valid (i.e., in a git repo)
