ci(rust): synchronize napi dependencies

[gautamsirdeshmukh]

Description

Dependabot split the tightly coupled napi-rs runtime and derive updates across #76 and #77. Either update alone produces an incompatible runtime/macro combination and breaks the Node.js build.

This change applies both updates together, keeping napi, napi-sys, napi-derive, and napi-derive-backend compatible.

Related Issues

Supersedes and closes #76 and #77.
