+fix: remove default "--app deployed" global flag from commands
+
+Commands running for a specific app must now provide the "app" argument:
+
+```diff
+  await SlackCLI.app.delete({
+    appPath: "my-app",
+    team: "T0123456789",
++   app: "deployed",
+  });
+```
+
+The options "local" or "deployed" or app ID all remain available to use.
