Shell Extended Glob Disabling

What: Automatically disables extended glob patterns in bash and zsh before executing commands to prevent unexpected shell expansion.

How to use:

# Runs automatically - no user action needed
# Before your command executes, Claude Code now runs:
# Bash: shopt -u extglob
# Zsh: setopt NO_EXTENDED_GLOB

Details:

• Prevents patterns like !(pattern), +(pattern), *(pattern) from expanding
• Only applies to bash and zsh shells
• Errors are silently suppressed to avoid breaking command execution
