add SHOPIFY_CLI_ENV=development for test commands

[phyllis-sy-wu]

WHY are these changes introduced?

Some unit tests fail when SHOPIFY_CLI_ENV=development is not set. Specifically, four tests in the removeDuplicatedPlugins suite in base-command.test.ts depend on BaseCommand.init() skipping registerCleanBugsnagErrorsFromWithinPlugins (which only runs when not in development mode). Without this skip, that function runs against mock plugins that have no root property, throws before removeDuplicatedPlugins can execute, and the assertions fail.

Context

There are three ways to run unit tests locally:

1. dev test
   • Defined in dev.yml.
   • For internal Shopify engineers.
   • SHOPIFY_CLI_ENV=development is already set in dev.yml, so tests pass after dev up.
2. pnpm test
   • Defined in package.json.
   • For both external contributors and internal engineers.
   • Previously did not set SHOPIFY_CLI_ENV=development, so four tests failed unless the caller exported the variable manually.
3. Direct invocation — pnpm vitest run
   • Same issue as above; requires manually setting SHOPIFY_CLI_ENV=development.

WHAT is this pull request doing?

• Sets SHOPIFY_CLI_ENV: 'development' in vite.config.ts under test.env, so the variable is applied to all vitest invocations (pnpm test, pnpm vitest run, and CI) on all platforms — without requiring a shell prefix or additional dependencies like cross-env.
• Removes the now-redundant test:unit script. After cucumber tests were removed, test and test:unit became identical (pnpm vitest run). Keeping both caused confusion with no benefit.
• Updates .github/workflows/tests-manual.yml to reference pnpm test instead of the removed pnpm test:unit.

How to test your changes?

Run the commands below on different branches:

dev up
unset SHOPIFY_CLI_ENV
pnpm test # or dev test
# Output

On main - reproduce the failure:
Output: 4 tests fail in base-command.test.ts > removeDuplicatedPlugins

On this branch - verify the fix:
Output: all tests pass
