`localStorage` not always available, causing TypeErrors

Current Behavior:

When a user loads a site with vidstack in an Android Mobile WebView, localStorage is not always available (depending on the WebView). Therefore the following error is raised:

TypeError: Cannot read properties of null (reading 'getItem')

Expected Behavior:

No error/exception is raised, localStorage is null-checked and ignored if null.

Steps To Reproduce:

Use an Android application that opens an embedded webview when opening a link.
Share a link to a page with vidstack.

Reproduction Link:
https://www.vidstack.io/player/demo?framework=react&view=player

Easiest way to reproduce:

• In Firefox, go to about:config, disable dom.storage.enable.
• Navigate to the demo page, it will crash.

Environment:

• Framework: React
• Meta Framework: Next.js
• Node: 20.11.0
• OS: Android 11
• Browser: Chrome Mobile WebView 128.0.6613

I've also got the same problem for a Nuxt.js project.
