Native Windows deployment: config file, service, signed auto-update

- internal/config: .env-style config file (gpu-turnstile.env next to the exe, -config flag or GPU_TURNSTILE_CONFIG); process env overrides file. - internal/service: Windows service via golang.org/x/sys/windows/svc — graceful SCM stop, 'service install/remove' commands, restart-on-failure recovery (also applies staged updates). First external dependency, Windows-only; Linux/Docker build unaffected (go.mod stays at 1.23). - internal/update: polls the Gitea releases API, verifies the Ed25519 signature of the downloaded binary against an embedded public key (openssl-signed by CI), swaps it in next to the running exe, and once the GPU lock is idle exits with code 3 so service recovery restarts onto the new version. Dev builds and empty pubkey never update. - CI: tag builds additionally produce gpu-turnstile.exe + .sig + .sha256 attached to a Gitea release. - LOG_FILE env var so the service has somewhere to log.
