fix: update slash command count and add /setup assertion in test

- Update slash_command_specs().len() assertion from 139 to 140.
  The /setup command added by this PR increased the spec count by 1
  but the test's expected count was not updated, causing CI failure.

- Add assert!(help.contains("/setup")) to the
  renders_help_from_shared_specs test so the new command is
  verified in the help output.

  Fixes CI Build ❌ and Test ❌ on #3218.
