Drop github.com/ncruces/go-sqlite3/embed import

ncruces/go-sqlite3 v0.33 replaced its embedded wasm runtime with a
pure-Go translation (via wasm2go) in the new module
github.com/ncruces/go-sqlite3-wasm. The embed subpackage that used to
initialize sqlite3.Binary at import time no longer exists, so the
blank imports break the build. SQLite is now wired in automatically
as a transitive dep.
