Note

Low Risk
Translation-only addition with no engine logic changes; risk is limited to incorrect Indonesian function/error strings affecting formula parsing for idID users.

Overview
Adds Bahasa Indonesia (idID) as a built-in HyperFormula language pack so formulas and cell errors can use Indonesian names (e.g. JUMLAH, JIKA, #BAGI0!).

The new src/i18n/languages/idID.ts dictionary mirrors other locales (errors, function aliases, NEW_SHEET_PREFIX: 'Lembar') and is re-exported from src/i18n/languages/index.ts for hyperformula/i18n/languages/idID imports. Docs now list 18 supported languages and include Indonesian in the supported-languages table; CHANGELOG records the addition under Unreleased.

Also adds .cursor/settings.json enabling the superpowers plugin (unrelated to i18n).

Cursor IDE config file accidentally committed

Low Severity

The .cursor/settings.json file is a Cursor IDE configuration file that was accidentally committed to the repository. It's not in .gitignore (which does exclude .idea/ and .vscode), so this will persist and affect all contributors who clone the repo.
