Add plan, feature-preview, and with-demo-data flags to store create dev

[amcaplan]

WHY are these changes introduced?

The hidden shopify store create dev command should accept the additional flags described in the Store management with AI Kit project brief. This PR implements the three that the Business Platform createAppDevelopmentStore mutation already supports.

WHAT is this pull request doing?

Wires three new flags through to the createAppDevelopmentStore mutation:

Flag	Backend variable	Notes
--plan (required)	priceLookupKey	Maps user-facing handles → backend price lookup keys (see below).
--feature-preview	developerPreviewHandle	Pass-through string (added to the mutation document); no canonical list since previews change over time.
--with-demo-data	prepopulateTestData	Previously hardcoded to false.

Plan mapping (canonical, lives in the new shared services/store/constants.ts — the backend argument is a plain string with no reusable enum; handles mirror the Dev Dashboard store-creation form):

--plan (handle)	priceLookupKey
basic	BASIC_APP_DEVELOPMENT
grow	PROFESSIONAL_APP_DEVELOPMENT
advanced	UNLIMITED_APP_DEVELOPMENT
plus	SHOPIFY_PLUS_APP_DEVELOPMENT

store info already mapped raw Shop.planName values (professional, unlimited, shopify_plus, …) to these public handles using its own copy of the taxonomy. Rather than leave that scattered, both mappings now sit side by side in constants.ts as two explicit per-direction maps — kept deliberately literal (not derived from one another) for readability. All plan data lives in one file while each command keeps its own lookup. This is why services/store/info/plan.ts appears in the diff; no behavior change to store info.

The plan, feature preview, and demo-data status are also surfaced in the success output and JSON result.

Deferred (need backend work in shop/world)

--country and --subdomain are intentionally not included — they require new backend support and are tracked in shop/issues-develop#22968:

• --country: Core already accepts country, but the BP mutation derives it from the org address rather than exposing an argument.
• --subdomain: no subdomain input exists at any layer.

The command remains hidden, so these flags aren't user-visible yet (no changeset).

How to test your changes?

• pnpm nx run store:type-check
• pnpm nx run store:lint
• Store package tests: cd packages/store && vitest run — 201 passing, including new coverage for the plan→priceLookupKey mapping, feature preview, demo data, and --plan validation (required + rejects invalid values).
