Closes #17

fix: scan nested skill directories up to 3 levels deep

scanDirectoryWithSkillMd only checked one level, missing grouped
structures like ~/.agents/skills/<group>/skills/<name>/SKILL.md

Now recurses into subdirs that don't contain SKILL.md, up to depth 3.

Also includes skillkit binary validation (isCrafterSkillkit).

Closes #16
