v0.1.1

v0.1.1: default to $HOME on macOS/Linux, prune .git, speed up walk

- system_roots() on non-Windows now defaults to the user's home directory
  instead of /, avoiding crawls of /proc, /sys, /System and other system trees
- Prune .git directories during discovery (thousands of objects, never a target),
  which makes home-directory scans across many repos noticeably faster
- Update README to document the platform-specific default scan root
