deploy: add login healthcheck wrapper

deploy/healthcheck/README.md

@@ -0,0 +1,14 @@
+`metin-login-healthcheck.sh` is a root-only operational check for the Debian VPS.
+
+What it does:
+- creates a temporary account in MariaDB
+- runs `metin_login_smoke` against auth and channel ports
+- verifies `AUTH_SUCCESS`, `EMPIRE`, and `LOGIN_SUCCESS4`
+- deletes the temporary account on exit
+
+Default paths and ports are tuned for the current VPS layout. Override with env vars if needed:
+- `RUN_AS_USER`
+- `SERVER_HOST`
+- `AUTH_PORT`
+- `CHANNEL_PORT`
+- `SMOKE_BIN`
