feat(eos): add accessibility

# Accessibility on /e/OS

/e/OS relies on Android’s accessibility framework but keeps everything deGoogled and open source. The official Android accessibility documentation (via Google) still applies, and the linked guides below cover:

- Getting started

- Screen readers (TalkBack)

- Display adjustments (magnification, page zoom, braille)

- Interaction controls (switch access, touch, voice)

- Audio & captions support

- Enabling/disabling TalkBack

- Updating accessibility apps via the regular /e/OS Updater

## Live Caption (VOSK-based)

/e/OS ships an alternative Live Caption powered by [VOSK](https://alphacephei.com/vosk/) instead of Google’s solution. It captures system audio in real time and shows the spoken text on-screen.

### Enable Live Caption

1. Open `Settings > Accessibility > Live Caption`.

2. Toggle **Live Caption** on.

### Tune Live Caption

1. Choose a language under `Settings > Accessibility > Live Caption > Languages`. The first download may take a few seconds.

2. Adjust caption style and fonts via `Live Caption > Caption preferences` or `Settings > Accessibility > Caption preferences`.

> The Live Caption language is independent from the system language and defaults to English (US).

## General

To learn about accessibility on /e/OS devices, go to [Android Accessibility](https://support.google.com/accessibility/android/). You may notice the URL contains "Google": it's because the Android Open Source Project is documented by them. Rest assured all the accessibility features you'll find in /e/OS are deGoogled and Open Source.

## Live caption

As Android's native live caption solution is based on a Google solution, we implemented our own solution, based on [VOSK](https://alphacephei.com/vosk/). When enabled this solution captures all system audio and display the corresponding text on screen so you can know what the video says.

### How to enable it

* Live caption can be activated by going to your `Settings > Accessibility > Live Caption`
