feat(skills): bundle minimum skill set from claude-skills into factory/skills/

Copies 8 standalone skills (active-platform, caveman, project-discipline,
pulling-before-work, setup-tasks, setup-wiki, using-tasks, using-wiki) from
~/projects/claude-skills/skills/ and all 14 superpowers sub-skills from the
installed plugin cache into factory/skills/superpowers/.

Adds skills install step to bootstrap.ps1: copies all factory/skills/
directories to ~/.claude/skills/ so users get the skill set automatically
without manual plugin install for the baseline set.
