Function plan_replacements

plan_replacements(
    entries: font_handle_entry[],
    choices: Map<string, string>,
    uuid_for_family: (family: string) => string,
    family_of_uuid?: (uuid: string) => string,
): {
    calls: { family: string; from: string; to: string }[];
    problems: { family: string; reason: string }[];
}
The substitute_font() calls for the chosen rows, and the rows that cannot be replaced. Several families may go to one target: that is the point (MyVivenda's Georgia, Helvetica and Lato all to a theme's FONT_4).

⚠️ A row whose TARGET is a family also being replaced in this OK is refused. substitute_font() matches references by uuid, so the calls would chain: "Georgia → Arial" leaves Georgia carrying Arial's uuid, and a later "Arial → Helvetica" sweeps Georgia into Helvetica too; a swap collapses both families onto one. Replacing into a family that is going away has no meaning to order around, so it is reported instead. family_of_uuid answers which family a target uuid is.
