/**
 * db.ts - Cross-runtime SQLite compatibility layer
 *
 * Provides a unified Database export that works under both Bun (bun:sqlite)
 * and Node.js (better-sqlite3). The APIs are nearly identical — the main
 * difference is the import path.
 *
 * On macOS, Apple's system SQLite is compiled with SQLITE_OMIT_LOAD_EXTENSION,
 * which prevents loading native extensions like sqlite-vec. When running under
 * Bun we call Database.setCustomSQLite() to swap in Homebrew's full-featured
 * SQLite build before creating any database instances.
