Subcommand routing

Parse the first argument from $ARGUMENTS:

Subcommand	Risk	AI-allowed	Behavior
`install`	🔴 destructive	❌ user-only	Modifies ~/.claude/settings.json + shell profile. Requires explicit `<command-name>cc-token-saver:setup-git-lite</command-name>` tag with `<command-args>install</command-args>`
`revert`	🔴 destructive	❌ user-only	Aggressive cleanup. Same gating as install
`status`	🟢 safe	✅ allowed	Read-only diagnostic
`dismiss-banner`	🟢 safe	✅ allowed	Suppresses the recommendation banner (preferences.json flag)
`undismiss-banner`	🟢 safe	✅ allowed	Re-enables the banner
`help`	🟢 safe	✅ allowed	Prints usage
(empty)	🟢 safe	✅ allowed	Run `status`, then append one-line usage hint: "Subcommands: install, revert, status, dismiss-banner, undismiss-banner, help"
