[bugfix] Add vite-define shim for Playwright i18n collection (#6906)

## Summary

Fixes the `ReferenceError: __DISTRIBUTION__ is not defined` error when
running i18n collection tests.

## Problem

PR #6879 added conditional menu commands based on distribution (hiding
memory unload commands in cloud). This introduced a dependency on
`isCloud` which uses the `__DISTRIBUTION__` Vite define variable in
`coreMenuCommands.ts`.

When Playwright's test runner imports this file during i18n collection,
it fails because Vite define variables are only replaced during Vite's
build/dev process, not during Playwright's TypeScript compilation.

## Solution

Created a simple shim (`scripts/vite-define-shim.ts`) that:
1. Defines all Vite define variables as global constants with default
values
2. Provides a minimal `window` shim for Node environment
3. Is imported at the top of `collect-i18n-general.ts` before any code
that uses these variables

This approach is simpler than:
- Creating a custom Babel plugin (attempted in this PR, see commit
history)
- Using `ctViteConfig` (only works for component testing, not regular
Playwright tests)
- Post-build regex replacement (fragile and error-prone)

## Test Plan

Run `pnpm collect-i18n` and verify:
- ✅ No more `ReferenceError: __DISTRIBUTION__ is not defined`
- ✅ No more `ReferenceError: window is not defined`
- ⏱️ Tests may timeout if dev server is not running on port 5173, but
that's a separate issue
