Moving this down to include the appleLibraries and supporting --apple without --android to build the TypeScript declaration file.

I haven't looked into this more, but it troubles me that we have to allow undefined symbols this way 🤔

[kraenhansen]

I deleted this again, the example builds without it 🤔 I have no idea why it was needed at that point in time 😕

Pull Request Overview

This PR updates Ferric to target napi.rs v3 by switching from the spawn-based CLI invocation to the new NapiCli API and updating dependency versions.

• Replaces the old spawn usage with NapiCli.build in generating TypeScript declarations.
• Consolidates the generation of TypeScript declarations and entrypoint for both Android and Apple libraries.
• Bumps dependency versions in package.json and Cargo.toml to align with napi.rs v3.

• Modifying process.env globally may lead to race conditions if generateTypeScriptDeclarations is called concurrently; consider isolating or synchronizing this change.

process.env.RUSTFLAGS = "-C link-arg=-undefined -C link-arg=dynamic_lookup";

• [nitpick] Since libraryName is derived from both android and apple library outputs, consider renaming it to more clearly convey its combined nature.

const libraryName = determineLibraryBasename([ ...androidLibraries.map(([, outputPath]) => outputPath), ...appleLibraries.map(([, outputPath]) => outputPath) ]);
