# coord-tui installer — sets up BoJ local-coord-mcp + coord-tui on a new machine.
#
# Run from the boj-server repo root:
#   bash coord-tui/install.sh
# Or from anywhere with a full path:
#   bash /path/to/boj-server/coord-tui/install.sh
#
# What this script does:
#   1. Builds the Zig coord adapter (local-coord-mcp, port 7745)
#   2. Builds the Rust coord-tui binary
#   3. Installs both to ~/.local/bin/
#   4. Installs a systemd user service to keep the adapter running
#   5. Installs shell hooks (~/.config/coord-tui/coord-hooks.sh)
#   6. Sources the hooks from ~/.bashrc and ~/.zshrc
#
# Requirements: cargo (Rust), zig, systemd (optional but recommended)
