I'm Bonk, and I've done a quick review of your PR.

This PR adds Node.js compatibility constants across multiple modules (async_hooks, process, sqlite, zlib, http2, events, _http_common, constants). I verified the constant values against current Node.js main source and found 4 issues:

1. [MED] process.features.uv: true — workerd uses KJ's event loop, not libuv. This should be false.
2. [MED] process.versions includes cjs_module_lexer — this is not a real process.versions key in Node.js (verified against src/node_metadata.h).
3. [LOW] process.versions is missing ngtcp2 and nghttp3 which are present in Node.js NODE_VERSIONS_KEYS_BASE.
4. [LOW] asyncWrapProviders includes QUIC_PACKET: 68 which does not exist in current Node.js main src/async_wrap.h.

All findings have been posted as inline review comments on PR #6568 with suggestions where applicable.
