# Usage:
#   curl -fsSL https://raw.githubusercontent.com/asheshgoplani/agent-deck/main/install.sh | bash
#
# Options:
#   --name <name>       Custom binary name (default: agent-deck)
#   --dir <path>        Installation directory (default: ~/.local/bin)
#   --version <ver>     Specific version (default: latest)
#   --skip-tmux-config  Skip tmux configuration prompt
#   --non-interactive   Skip all prompts (for CI/automated installs)
#   --pkg-manager <mgr> macOS package manager: 'brew' or 'port' (default: auto-detect)
#
# The installer will:
#   1. Download and install the agent-deck binary
#   2. Check for tmux (offer to install if missing) - REQUIRED
#   3. Check for jq (offer to install if missing) - Optional, for session forking
#   4. Configure ~/.tmux.conf for mouse scrolling & clipboard - Optional
#
# Supported platforms:
