Add a new feature page/route to this SvelteKit + Svelte 5 app following baca-quran.id conventions. Use whenever the user asks to add a new page, new route, new feature with its own URL (e.g. "/kalender-hijriyah", "/khatam-tracker"), or expose a feature from the homepage. Covers route creation, prerender registration, sitemap, SEO, breadcrumb, homepage entry, i18n, and verification.
Add or update an i18n translation key in baca-quran.id. Use whenever the user asks to add a translation, change a label, add a new string for a UI element, or fix Indonesian/English wording. Ensures both id.json and en.json stay in sync and the key is consumed reactively.
