Extended the CLI hook to handle compound commands — piped commands, && chains, and semicolons are now split and each part checked individually against the approved reads list. This means Claude Code can auto-approve things like git status && git diff without needing each compound form explicitly listed. Consolidated the cli-hook subcommands into a cleaner structure.

Also switched the cli-reads lookup to pure JavaScript to avoid shell overhead on each hook invocation, and made assist update run npm install after pulling to ensure dependencies stay in sync.
