/**
 * Android bootstrap — wires WebMailxDB + WebMessageStore + GmailApiWebProvider + WebMailxService
 * into the mailxapi bridge. This replaces Node.js backend for Android WebView.
 *
 * On Android, everything runs in the same JavaScript context:
 * - wa-sqlite for metadata (via WebMailxDB)
 * - IndexedDB for message bodies (via WebMessageStore)
 * - Gmail/Outlook sync via REST APIs (plain fetch — no native bridge needed)
 * - IMAP accounts use BridgeTransport (via MAUI TCP bridge) — not yet implemented
 *
 * The existing client UI (app.ts, components/) is completely unchanged —
 * it calls window.mailxapi.* which this module provides.
