/**
 * Keep prompts in step with the tools that are actually loaded.
 *
 * With selective loading (--modules, MODULES), a prompt that says "call
 * treasury_query_fiscal_data" when Treasury isn't loaded sends the model after
 * a tool that doesn't exist. The filter:
 *
 * - drops every line that mentions a known tool which isn't loaded, wherever
 *   the name appears in the line (list item, numbered step, prose)
 * - renumbers numbered steps after a removal so they stay 1, 2, 3, …
 * - hides a prompt when it mentions tools but none of them are loaded and it
 *   doesn't name a loaded module either
 *
 * "Known" tools are those of every module that could be loaded, plus
 * deprecated aliases. Other snake_case words, such as dataset names like
 * debt_to_penny, are left alone.
