Fix store auth scope parsing for space-separated input

[RyanDJLee]

Summary

Fixes shopify store auth failing with "Shopify granted fewer scopes than were requested" on Windows PowerShell despite a successful OAuth code exchange.

• parseStoreAuthScopes split on commas only, but Windows PowerShell can transform comma-separated CLI args into space-separated strings before they reach Node.js
• This caused "read_products read_inventory" to be treated as a single unrecognized scope
• The server-side parser (Access::ScopeSet.parse_scopes) already handles both delimiters via /[ ,]/ — the CLI parser now matches that behavior

Root cause

When a partner runs:

shopify store auth --scopes read_products,read_inventory

PowerShell's argument handling can deliver "read_products read_inventory" (space, no comma) to process.argv. The CLI's parseStoreAuthScopes splits on , only, producing ["read_products read_inventory"] — one scope element. The server parses both formats correctly and returns scope: "read_products,read_inventory" (comma-separated). The CLI then fails validation because the single requested scope "read_products read_inventory" isn't in the granted set {"read_products", "read_inventory"}.

Confirmed via partner verbose logs showing the debug output with scopes read_products read_inventory (no comma in scopes.join(',') output, proving a single-element array) and analytics args "--scopes read_products read_inventory".

Changes

• scopes.ts: .split(',') → .split(/[\s,]+/) to handle both comma and space delimiters
• scopes.test.ts: 3 new tests covering space-separated input, mixed delimiters, and the end-to-end PowerShell scenario

Test plan

• Existing 6 unit tests in scopes.test.ts pass (no regressions)
• New test parseStoreAuthScopes splits space-separated scopes fails before fix, passes after
• All 11 integration tests in index.test.ts pass
• Manual: shopify store auth --scopes read_products,read_inventory on Windows PowerShell
• Backport to stable/3.93 for partner unblock

Pull request overview

This PR fixes shopify store auth scope parsing so PowerShell-transformed --scopes arguments (spaces instead of commas) are correctly interpreted, matching the server-side delimiter behavior and preventing false “granted fewer scopes” failures.

Changes:

• Update parseStoreAuthScopes to split scopes on whitespace and/or commas.
• Add unit tests for space-separated scopes and mixed delimiters.
• Add a test intended to cover the PowerShell end-to-end scenario for requested vs. granted scope validation.

File	Description
packages/cli/src/cli/services/store/auth/scopes.ts	Adjusts scope parsing to support whitespace-delimited lists (in addition to commas).
packages/cli/src/cli/services/store/auth/scopes.test.ts	Adds test coverage for the new parsing behavior and the reported PowerShell scenario.

• parseStoreAuthScopes now accepts both comma- and whitespace-delimited scope lists, but the AbortError help text in this function still says "Pass --scopes as a comma-separated list." Please update the guidance to reflect the supported formats (comma and/or whitespace), so the error message stays accurate for users on PowerShell and other shells.

    .map((scope) => scope.trim())
    .filter(Boolean)

This test description claims to cover the PowerShell space-separated input scenario, but the test passes an already-split requestedScopes array. To actually cover the reported bug (and match the PR description), build requestedScopes via parseStoreAuthScopes('read_products read_inventory') or rename the test to reflect what it currently asserts.

Suggested change

	['read_products', 'read_inventory'],
	parseStoreAuthScopes('read_products read_inventory'),
