#!/usr/bin/env bash
# -----------------------------------------------------------------
# dev.sh — one-command dev environment for TTRPG Tavern
#
# Starts Qdrant (if not already up), kills any stale dev node
# process, and launches the app with auto-reload on file changes.
#
# Uses prod LLM services (llama-server :8180, llama-director :8182,
# ollama :11434) — no extra GPU containers needed.
#
# To swap the Director to a reasoning model, set DIRECTOR_MODEL_FILE
# before starting the prod stack:
#   DIRECTOR_MODEL_FILE=Qwen3-32B-Thinking-Q5_K_M.gguf docker compose -f docker-compose.prod.yml up -d
# The app strips <think>/<thinking> tags automatically.
#
# Usage:
#   ./dev.sh          # start (or restart) dev
#   npm run dev       # same thing via package.json
