Switch to native Claude Code installer and add update command

Browse source 
Replace the deprecated npm installation with the native installer. The
binary is installed to /usr/local/bin so it survives the home directory
bind mount at runtime.

Add a 'claude update' subcommand that rebuilds the image with the latest
Claude Code binary and removes all existing containers.

Disable the in-container auto-updater since the binary lives in the
read-only image layer.
