The bootstrap text advertised a configDir-based skills path that didn't
match the runtime path (resolved relative to the plugin file). Tests
used yet another hardcoded path and referenced a nonexistent lib/ dir.
- Remove misleading skills path from bootstrap text; the agent should
use the native skill tool, not read files by path
- Fix test setup to create a consistent layout matching the plugin's
../../skills resolution
- Export SUPERPOWERS_SKILLS_DIR from setup.sh so tests use a single
source of truth
- Add regression test that bootstrap doesn't advertise the old path
- Remove broken cp of nonexistent lib/ directory
