## Summary
Adds a compile-time `__IS_NIGHTLY__` constant that detects whether the
build is from the main branch (nightly) or a core/* branch (RC/stable).
The detection logic in vite.config.mts auto-detects based on
`GITHUB_REF_NAME === 'main'` in CI, with explicit override support via
`IS_NIGHTLY` environment variable. Exports `isNightly` from
`src/platform/distribution/types.ts` for use throughout the codebase.
Includes unit tests for the detection logic.

## 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
