feat: one-line installer + configurable reconnect attempts#33
Merged
Conversation
install.sh handles install, update, and uninstall in a single curl | sudo bash. SHA256-verifies the release tarball against checksums.txt, creates a dedicated flashduty service user and hardened systemd unit on Linux, and falls back to a binary-only install on macOS / non-systemd hosts. Env file is never overwritten on re-install. Matching CI workflow runs shellcheck, parse checks, and a 10-scenario Docker smoke test. Separately, wire --max-attempts / FLASHDUTY_RUNNER_MAX_ATTEMPTS through the WebSocket client so operators can raise or uncap the reconnect limit (0 = unlimited, default 30). READMEs lead with the one-liner above the manual install block; full design spec is checked in at docs/superpowers/specs/. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
