/**
 * Generates the help text for the `nmr` CLI. Renders only nmr commands —
 * names from the workspace and root registries, excluding hooks (`*:pre`,
 * `*:post`).
 *
 * When `packageDir` is provided, tier-3 entries from that package's
 * `package.json:scripts` that match a registry name in the active section
 * are inlined as overrides: the registry value is replaced with the
 * override value and the row's command name is suffixed with `*`. The
 * active section is the root section when `useRoot` is true (root cwd
 * or `-w`), otherwise the workspace section. A footnote is appended once
 * if any override marker was rendered.
