fix(napi): receive raw pointer out parameters

[GrapeBaBa]

Motivation

Node-API returns several values through pointer-sized C out parameters. The previous bindings passed addresses of higher-level Zig struct or wrapper storage to some of these APIs, so Node-API wrote raw pointer or handle bits into the wrong fields instead of a correctly typed raw slot. This could corrupt returned Node version data and TypedArray or DataView backing ArrayBuffer wrappers. Receiving the exact C values first, then copying or wrapping them only after a successful call, preserves both the C ABI and the Zig wrapper invariants. Unsupported TypedArray tags must likewise become a normal conversion error rather than an enum-conversion trap.

Summary

• receive the Node version pointer through its own raw out slot before copying the version structure
• receive TypedArray and DataView backing ArrayBuffer handles as raw napi_value values
• construct Value wrappers only after successful Node-API calls
• report unsupported Node-API TypedArray element types as UnsupportedTypedarrayType instead of trapping during enum conversion
