[BUG]: Speech Recognition stops automatically despite continuous mode enabled

### Bug Description

Problem Description
When using the Web Speech API (SpeechRecognition / webkitSpeechRecognition) with recognition.continuous = true, speech recognition still stops automatically after a short period of silence or inactivity.
This behavior breaks the expected continuous listening functionality, as recognition should remain active until it is explicitly stopped by the application.

Steps to Reproduce
1. Initialize SpeechRecognition
2. Enable continuous mode
3. Start recognition
4. Wait for silence or inactivity
5. Recognition stops automatically

Expected Behavior
Recognition should continue listening until manually stopped.

Actual Behavior
Recognition stops automatically due to silence, timeout, or internal browser reset.

Environment
1. Browser: Chrome / Edge
2. Frontend: TypeScript web application
3. API: Web Speech API

Workaround
Restart recognition manually inside the onend event.

### Code of Conduct

- [x] I have joined the [Discord server](https://discord.gg/hjUhu33uAn) and will post updates there
- [x] I have searched existing issues to avoid duplicates

No project files or tests are named. Start by locating the SpeechRecognition integration and its onend handler, then reproduce the Chrome/Edge silence behavior with continuous mode enabled. Done means recognition remains usable during silence or the issue documents a verified browser limitation and an appropriate application-level outcome.
