Original PR and review history: #8643.

WHY are these changes introduced?

Fixes https://github.com/shop/issues-develop/issues/23691

Explicit theme profiling environments need the same ordered batch contract.

WHAT is this pull request doing?

Preserve the native Speedscope artifact and wrap explicitly named environments in one result object. Separate service data from presentation and keep failures on the shared fatal path.

The public output follows docs/cli/json-output.md; explicitly named environments use one {environments: [...]} object.

How to manually test your changes?

shopify theme profile --store example.myshopify.com --json
shopify theme profile --json-schema

Checklist

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.
