Fix claude-code install at unsupported location (3.0.0)

The previous install copied the launcher shim from $HOME/.local/bin to
/usr/local/bin, which trips Claude Code's "unsupported install
location" check (the auto-updater can only manage paths matching the
canonical .claude/local/ + .local/bin/ layout) and breaks the launcher,
which expects supporting files at its original $HOME-relative path.

Run the official native installer with HOME pointed at the remote
user's home, producing the canonical layout, then chown the result.
Same root-not-sudo pattern as the nvm feature. Major bump because the
binary location changes.
