* Implement Android's Looper

Looper handles thread messaging. This is used by extensions when they
want to enqueue actions e.g. for sleeping while WebView does someting

* Stub WebView

* Continue stubbing ViewGroup for WebView

* Implement WebView via Playwright

Supports Yidan

For Bokugen

* Stub a KCef WebViewProvider

* Initial Kcef Webview implementation

Still buggy, on the second call it just seems to fall over

* Format, restructure to create browser on load

This is much more consistent, before we would sometimes see errors from
about:blank, which block the actual page

* Implement some small useful properties

* Move inline objects to class

* Handle requests in Kcef

* Move Playwright implementation

* Document Playwright settings, fix deprecated warnings

* Inject default user agent from NetworkHelper

* Move playwright to libs.versions.toml

* Lint

* Fix missing imports after lint

* Update server/src/main/kotlin/suwayomi/tachidesk/server/ServerSetup.kt

* Fix default user agent set/get

Use System.getProperty instead of SystemProperties.get

* Configurable WebView provider implementation

* Simplify Playwright settings init

* Minor cleanup and improvements

* Remove playwright WebView impl

* Document WebView for Linux
