Switch Claude Code install to shell CLI and defer API key setup

- Use non-interactive 'claude plugin ...' commands instead of the
  interactive /plugin slash commands
- Remove the interactive plugin-config-screen API key step
- Move API key setup into a shared 'Configure the API key' section
  after install, used by both Claude Code and Codex
