The .github/workflows/ directory is no longer needed.

-# Deploys ArchNest (frontend + backend + guacd) to racknerd1 via Docker Compose.
-#
-# Triggers:
-#   - push to main (automatic)
-#   - manual run from the Actions tab (workflow_dispatch)
-#
-# Required GitHub Actions repo secrets (Settings -> Secrets and variables -> Actions):
-#   RACKNERD_HOST    - racknerd1 hostname or IP the runner can SSH to
-#   RACKNERD_USER    - deploy SSH user (must be in the docker group)
-#   RACKNERD_SSH_KEY - private SSH key (PEM) for that user
-#   RACKNERD_PORT    - SSH port (optional, defaults to 22)
-#
-# One-time host setup (NOT done by this workflow, see README Deployment section):
-#   - Docker + Docker Compose installed, deploy user in the docker group
-#   - mkdir -p /opt/archnest
-#   - Create /opt/archnest/.env from .env.example with real generated secrets
-#     (ARCHNEST_JWT_SECRET, ARCHNEST_SECRET_KEY, ARCHNEST_GUAC_CRYPT_KEY, ...).
-#     This workflow refuses to deploy if that file is missing, and never
-#     overwrites it, so live secrets/data are safe across deploys.
