* fix(cli): preserve literal Markdown table facts
* test(cli): retain capacity diagnostics through Markdown escaping
* fix(cli): keep intraword underscores readable in Markdown tables
Underscore runs between letters or digits cannot open or close CommonMark emphasis, so escaping them only adds noise to identifiers such as source_index and invalid_request in raw Markdown. Escape underscore runs only at word boundaries and restore the original diagnostic assertions.
When formatting arrays of objects that have no own enumerable keys as
Markdown, formatObjectTable derives empty headers and outputs a malformed
table with an invalid delimiter row. Require at least one item with keys in
isObjectArray and fall back to JSON serialization when headers are empty.
