+/**
+ * TerminalGateway
+ *
+ * WebSocket gateway for real-time PTY terminal sessions.
+ * Uses the `/terminal` namespace to keep terminal traffic separate
+ * from the main WebSocket gateway.
+ *
+ * Protocol:
+ * 1. Client connects with auth token in handshake
+ * 2. Client emits `terminal:create` to spawn a new PTY session
+ * 3. Server emits `terminal:created` with { sessionId }
+ * 4. Client emits `terminal:input` with { sessionId, data } to send keystrokes
+ * 5. Server emits `terminal:output` with { sessionId, data } for stdout/stderr
+ * 6. Client emits `terminal:resize` with { sessionId, cols, rows } on window resize
+ * 7. Client emits `terminal:close` with { sessionId } to terminate the PTY
+ * 8. Server emits `terminal:exit` with { sessionId, exitCode, signal } on PTY exit
+ *
+ * Authentication:
+ * - Same pattern as websocket.gateway.ts and speech.gateway.ts
+ * - Token extracted from handshake.auth.token / query.token / Authorization header
+ *
+ * Workspace isolation:
+ * - Clients join room `terminal:{workspaceId}` on connect
+ * - Sessions are scoped to workspace; cross-workspace access is denied
