fix: address PR review — correct path mismatch, relocate tests

1. Rename pi-extension/ to .pi-extension/ to match Pi auto-discovery
   convention. Update root README install instructions to reference
   correct path and install.sh workflow instead of non-existent
   .pi-extension/extensions/cli-anything/.

2. Move test_skill_generator.py from .pi-extension/cli-anything/tests/
   to cli-anything-plugin/tests/ (next to skill_generator.py) so it
   runs standalone without fragile parent-navigation fallbacks.
   Update install.sh to copy tests during global install.

31/31 pytest tests pass.
