A workspace .env file could set connector endpoint variables for Matrix, Mattermost, IRC, or Synology-related connectors and redirect runtime traffic away from the operator-configured endpoint.

Workspace .env loading now blocks those endpoint variables, including per-account Matrix homeserver suffixes and generic base-url/API-host style overrides. Trusted global runtime dotenv loading remains separate.
