# Command Palette - Fuzzy Command Launcher for Zsh
# ============================================================================
# A Raycast/Alfred-style command palette for the terminal
#
# Features:
# - Search aliases, functions, recent commands
# - Search bookmarked directories
# - Search dotfiles scripts
# - Quick actions (edit config, reload shell, etc.)
#
# Keybinding: Ctrl+Space (configurable)
#
# Requirements: fzf
#
# Add to .zshrc:
# source ~/.dotfiles/zsh/functions/command-palette.zsh
