rtk hook rewrites grep to ripgrep: BRE \( \| patterns and --include globs break

Context: a Claude Code hook (rtk) transparently rewrites Bash grep calls through ripgrep to save tokens.

Symptoms: - grep -n "router\.\(get\|put\)(" fails with "rg: regex parse error: unclosed group" because ripgrep uses Rust regex, where \( is a literal paren and ( opens a group. - grep -rn x --include=*.ts fails in zsh with "no matches found: --include=*.ts" because the unquoted glob is expanded by zsh before grep runs.

Fix: - Run the original command unrewritten: rtk proxy grep -nE "Router\.(get|put)\(" file - Use ERE (-E) syntax, and quote globs: --include="*.ts". - For recursive search with dir exclusions: rtk proxy grep -rIl pattern --exclude-dir=node_modules .
