/**
 * The creator's category tags for the game's portal listing, read out of the project's work
 * copy (`worldProfileData.categories`) — the CLI lane's equivalent of the Creator publish
 * dialog's category chips.
 *
 * Three distinct messages, mirroring the web lane's precedence exactly:
 *  - `undefined` (key not declared): the server decides — a game with no tags yet is
 *    AI-classified at publish; a game that already has tags keeps them.
 *  - a non-empty array: this exact set wins, replacing whatever is stored.
 *  - an empty array: an explicit "no tags" — clears stored tags AND suppresses the
 *    auto-classification a missing key would trigger.
 *
 * game.json wins over world.json for the same key, matching `readFaviconOverride` — the
 * split-format rule means `worldProfileData` may live in either file.
 *
 * Best effort, like the favicon override: a missing, unreadable or malformed file means
 * "not declared", never an error. Non-string and blank entries are dropped; the server caps
 * the count and canonicalizes against the live taxonomy.
