[Do not merge] Add JSON infrastructure sample command

[gonzaloriestra]

WHY are these changes introduced?

This disposable sample validates the finite-command infrastructure introduced by the PRs below it in the stack.

WHAT is this pull request doing?

• Adds a hidden kitchen-sink json-output command.
• Emits diagnostic and progress side events to stderr.
• Prints a validated human or JSON result.
• Exposes the result type through --json-schema and command help.
• Adds --fail to exercise structured JSON errors.

How to test your changes?

pnpm shopify kitchen-sink json-output
pnpm shopify kitchen-sink json-output --json
pnpm shopify kitchen-sink json-output --help
pnpm shopify kitchen-sink json-output --json-schema
pnpm shopify kitchen-sink json-output --json --fail

Checklist

• I've considered possible cross-platform impacts (Mac, Linux, Windows)
• I've considered possible documentation changes
• I've considered analytics changes to measure impact
• The change is user-facing — this is a hidden, disposable sample and intentionally has no changeset

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.
