Add typed JSON output to app execute

[isaacroldan]

WHY are these changes introduced?

Let scripts read GraphQL results from app execute. Related to #23671.

WHAT is this pull request doing?

Add --json with native {data, extensions?} results and shared fatal errors with GraphQL details. With --output-file, write the result to the file and return an absolute {path, format} receipt. Preserve text output and leave existing files unchanged on GraphQL failure.

For query { shop { name } }, normal stdout follows the existing success banner:

{"shop":{"name":"Test Shop"}}

The matching --json result is:

{"data":{"shop":{"name":"Test Shop"}}}

The JSON result also includes native extensions when the API supplies them.

How to manually test your changes?

Use a linked test app installed on a development store.

1. Run shopify app execute --query 'query { shop { name } }' --store <store>.myshopify.com --json --no-input > result.json. Check that stdout contains one object with data.shop.name.
2. Add --output-file query.json. Check that stdout contains {path, format} and the file contains the GraphQL result. Repeat without --json to compare existing text and file output.
3. Run an invalid query with --json --output-file query.json. Expect one error object, a nonzero exit, and an unchanged file. Run shopify app execute --json-schema to inspect the contract.
