refactor(testing): replace custom Deno adapter with @std/expect and @std/testing/bdd (#821)

Remove the 248-line custom Deno test adapter that reimplemented
describe/it/expect and use Deno's standard library instead.
The deno.test.ts file now follows the same pattern as node.test.ts
and bun.test.ts.
