# Optional dev-container image for Claude Code Agent Monitor.
# Node 22 to match the production Dockerfile and the project's engines.
# Adds the native-addon toolchain (better-sqlite3 builds via node-gyp) plus
# Python 3 (statusline.py and helper scripts) and the sqlite3 CLI.
#
# This image is ONLY used by Dev Containers / Codespaces. Host-based development
# (npm run dev / npm start) is unaffected.

# node-gyp needs python3 + a C/C++ toolchain to compile better-sqlite3.
# python-is-python3 makes `python` resolve to python3 for node-gyp.
# sqlite3 is handy for inspecting the dashboard DB during development.
