tooling: install script, workspace file, and dev-restart helper

- install.py — idempotent setup script (venv, systemd service, linger,
  auth checks); supports --check for read-only status inspection
- .stignore — exclude .venv and runtime dirs from Syncthing so each
  host maintains its own machine-local venv
- Cortex_and_Inara.code-workspace — VS Code workspace (service, personas,
  docs folders; launch config for uvicorn --reload)
- dev-restart.sh — SSH wrapper to restart Cortex on the gaming laptop
  and tail logs; supports restart / logs / status subcommands
