Run function GraphQL typegen with the project package manager

[dmerand]

What

Use the function project's package manager when running GraphQL type generation for JavaScript functions.

Why

buildGraphqlTypes was hard-coded to npm exec. That breaks function projects that use a different package manager, especially when the function lives inside a workspace and the lockfile is only present above the function directory.

How

• add a shared cli-kit helper that maps a directory to the right binary invocation
• use that helper when running graphql-code-generator for JS functions
• cover npm, pnpm workspace, yarn, and bun command shapes

Testing

Create or use a JS function extension in a non-npm project and run shopify app function build. GraphQL type generation should run through that project's package manager instead of npm exec.

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
