Add skill-manager skill (migrated from skill-creator) with deploy action

- Skill content moved from ~/.agents/skills/skill-creator, renamed to skill-manager
- New deploy CLI action: installs any skill via absolute-path symlinks (or copies)
  into $HOME/.agents/skills, $HOME/.claude/skills and $HOME/.cline/skills
- Taskfile + shell module wrappers (task deploy / cli:deploy)
- SKILL.md: deploy docs, origin-repository/origin-path metadata
