fix(install): install Claude Code via official native installer, not npm

Browse Source 
Uniformizes point 1: install.sh fresh-machine branch used npm, but npm
is no longer a documented Claude Code channel (official quickstart lists
Native/Homebrew/WinGet/apt only) and collides with the native symlink.
Switch the fresh-install path to the recommended native installer,
matching install-plugins.sh which already points to the native channel.

- install.sh: fresh install via `curl -fsSL https://claude.ai/install.sh
  | bash`; ensure ~/.local/bin on PATH for the auth/verify steps.
- skip-if-present guard unchanged.
- fix stale node/npm prerequisite comment (npm now serves the plugins
  step, not the Claude Code install).
