Add typed JSON output to app dev clean

[isaacroldan]

WHY are these changes introduced?

Let scripts read the dev-preview cleanup outcome. Related to #23668.

WHAT is this pull request doing?

Add --json with app identity and the canonical store domain, or null for local/unknown domains. Reject missing deletion data before reporting success.

Text: Dev preview stopped.
JSON: {"status":"success","app":{"name":"Example","clientId":"client-id"},"storeDomain":"example.myshopify.com"}.

Interactive JSON prompts need #8812. Successful postrun output is tracked in the shared issue note.

How to manually test your changes?

Use a linked test app and a development store.

1. Run shopify app dev clean --store <store>.myshopify.com --json --no-input > result.json. Check one success object with the correct app and store.
2. Repeat without --json; check the existing success banner. Use an inaccessible store with --json; expect one error object and a nonzero exit.
3. Run shopify app dev clean --json-schema to inspect the contract.

Note for future consistency work: we have store domain consistency rules, but I wonder if it's worth making them re-usable in the code rather than re-implementing in each schema?

to be honest, i don't think we need a regex for this? it can be a generic zod.string() 🤔
I'll update it.
