Switch sqlite to use Bun

[karlhorky]

• Bun zero-dependency sqlite https://x.com/puruvjdev/status/1807442339989725587
• And maybe Bun for everything else too?
  • Bun zero-dependency PostgreSQL client https://x.com/jarredsumner/status/1809997817961972174

Alternative:

• Switch to node:sqlite lib,src,test,doc: add node:sqlite module nodejs/node#53752
  • once it's released, Node.js 22.4.1 doesn't have it yet (CodeSandbox) and 22.5.0 probably won't have it either
