await analytics.track() produces TS80007 because Analytics interface returns void instead of Promise<void>

[muhammedaksam]

Describe the bug

Using await analytics.track(...) (and page, identify, setEnabled) produces TS80007: 'await' has no effect on the type of this expression.
The Analytics interface in @wxt-dev/analytics declares all methods as returning void, even though the background implementation is async (returns Promise<void>). The frontend implementation returns void. Since Promise<void> is assignable to void, there's no implementation error — but users calling await analytics.track() see TS80007 because the declared return type is void.

Reproduction

1. Create a WXT project with @wxt-dev/analytics configured
2. In any entrypoint (popup, options, content script, etc.), call await analytics.track('my_event')
3. Observe TS80007 in the editor or type checker

Steps to reproduce

1. npm create wxt@latest -- wxt-analytics-test
2. cd wxt-analytics-test
3. npm i @wxt-dev/analytics
4. Add analytics config to app.config.ts
5. In an entrypoint: await analytics.track('test')
6. npx tsc --noEmit
