chore(skills): remove agent-cli configuration and fix minor typos

Remove `docs/agents/agent-cli.md` and all references to it from
`setup-skills/SKILL.md` (contents list, docs files list, and the
Agent CLI block template). Fix typo "languagee" → "language" in
`setup-skills/SKILL.md` and "labels" → "label" in
`implement-issue/SKILL.md`.
