+ * Desktop/CLI-only and TUI-only slash commands that do NOT function on mobile
+ * (issue #574). Source of truth for the backend `cli_only` / TUI-only flags
+ * returned by `commands.catalog`.
+ *
+ * Two consumers:
+ * 1. The slash-command suggestion menu hides these (so users don't discover
+ *    dead commands).
+ * 2. [com.m57.hermescontrol.ui.chat.ChatViewModel.handleSlashCommand] blocks
+ *    them at dispatch time (issue #576, deliverable #3) — a user who types one
+ *    anyway gets a clear "not supported on mobile" message instead of a doomed
+ *    RPC that produces TUI-only output or a confusing error.
