#!/usr/bin/env bash
# One-time installer for claude-mode (Linux / macOS).
#
# Installs to ~/.claude-mode, symlinks the entry point into ~/.local/bin, and
# adds a marked block to your shell rc for the `claude` wrapper.
#
# Idempotent: safe to re-run to upgrade. Existing presets are kept unless
# --force is passed. ~/.claude/settings.json is NOT touched here - only by an
# actual `claude-mode <mode>`.
