Open links to posts in app

[brckd]

1. Environment

• Device: [Pixel 6a]
• OS: [Android 15]
• APP: [0.10.1]

2. Describe the feature request
It's common for blog posts to link to other posts of the same blog. Currently, these open in the browser and make the user lose the clean reading experience of Read You.

I propose that links to posts of any of the registered RSS feeds should be opened in the app. Feeds that enable Parse full content should also be able to open posts that aren't listed in the RSS feed but can clearly be assigned to it.
