build(deps): bump napi to 3 in code-validator guest host

Bump napi and napi-derive together to v3 (they are version-coupled);
napi-build stays at v2 (no v3 exists). No Rust code changes are needed —
the 3.x API used by the host crate is source-compatible.

napi-derive 3 makes `napi build` emit JSDoc into the generated
src/code-validator/guest/host/index.d.ts, which is not Prettier-formatted.
That file is a build artifact (the hand-written canonical types live in
src/code-validator/guest/index.d.ts), so it is now gitignored and
prettierignored, matching how other generated *.d.ts files are handled.
