refactor: migrate from node-sqlite3-wasm to better-sqlite3

Browse Source 
Replace all db.run(sql, [params]) calls with db.prepare(sql).run(...params)
across all source modules and test files. Also remove the node-sqlite3-wasm
import from tests/db.test.ts and update the type annotation accordingly.
