build: add node-gyp to devDependencies to resolve sharp source-build failures

[abstraction]

Current behavior

I hit a hard crash running npm i on Node LTS. Turns out if you have libvips installed, sharp skips the prebuilt binaries. It tries to compile from source instead.

Quartz already pulls in node-addon-api as a dependency through @parcel/watcher (ref). Sharp finds it without an issue. But node-gyp is missing entirely.

This completely breaks setup if the user's system forces a source build.

Expected behavior

Users can run npm i or pnpm i and get a working setup out of the box.

Solution

I added node-gyp to devDependencies. I left node-addon-api out because @parcel/watcher already brings it into the tree, and the sharp build succeeds with it as-is.

Pulling in node-gyp adds some weight to the initial install. But it stops the setup from crashing for common dev environments (mac too, i guess).

Environment

• Node version: 24.20.0 (LTS) and 26.7.0 (checked as well)
• OS: Arch (7.1.8-arch1-3)
• Package manager: npm and pnpm
