#!/usr/bin/env bash
# install.sh — instaleaza puntea Discord -> Claude Code pe LXC 171 (claude-agent).
#
# IDEMPOTENT: se poate rula de cate ori vrei. Nu suprascrie niciodata
# ~/.claude-discord/env (acolo sta token-ul completat de om).
#
#   ./ops/install.sh            # instaleaza / actualizeaza, NU porneste serviciul
#   ./ops/install.sh --start    # in plus porneste serviciul (cere DISCORD_TOKEN completat)
#
# Ce face:
#   1. ~/.claude-discord/ cu 0700 si logs/
#   2. env 0600 din ops/env.example (doar daca lipseste)
#   3. venv + dependinte din requirements.txt
#   4. loginctl enable-linger (serviciul de utilizator trebuie sa supravietuiasca logout-ului)
#   5. symlink unit -> ~/.config/systemd/user/claude-discord.service
#   6. intrare de crontab pentru logrotate
#   7. systemd-analyze verify + enable
