/**
 * Helper for {@link createTuiCommandHandler}: when the user types an unknown
 * slash command in the TUI, check whether the name matches a saved workflow
 * and, if so, rewrite the input into a natural-language prompt that
 * deterministically triggers the `workflow` tool.
 *
 * Why a rewrite and not a direct execution?
 *   Slash commands in xopc are handled by the chat-commands framework whose
 *   handlers return text shown back to the user — there is no hook to "inject
 *   the result as the next user message and start an agent turn". So the
 *   shortest reliable path is to turn `/audit_repo` into the same plain-text
 *   request the model already knows how to handle.
 *
 * Why catalog the workflow list at the TUI layer?
 *   The catalog reads `~/.xopc/workflows/` synchronously (single `readdir`),
 *   so the slash dispatch stays sync and the user sees no latency. The lookup
 *   only runs for inputs that started with `/` and didn't match any built-in
 *   or extension command, so the cost is negligible.
 *
 * Built-in TUI command names that overlap with a workflow file name keep their
 * existing TUI behaviour — the slash dispatcher matches the built-in switch
 * cases before this helper is consulted.
