Research direction

Start by tracing IsEngineInstalled() in src/UI/Features/Video/TextToSpeech/TextToSpeechViewModel.cs and compare the existing Piper flow in DownloadTtsWindow. Review the proposed installer area and SeVideoTextToSpeech.cs for the install-path setting. Done means AllTalk can be installed, started, detected as ready, and optionally auto-started when selected.

Written by the indexing model from the issue text.

Description

Problem

AllTalk TTS requires manual installation (Python, git clone, pip install, server startup). When AllTalk is not running, SE only shows a message with a GitHub link.

Current behavior

IsEngineInstalled() checks if AllTalk server responds within 2 seconds. If not, shows dialog: "AllTalk requires running local AllTalk web server. Read more?" linking to GitHub.

Proposed solution

Add automated installer similar to existing Piper download (DownloadTtsWindow):

Detect Python installation (check PATH, common locations)
Clone AllTalk repo (https://github.com/erew123/alltalk_tts)
Install Python dependencies (pip install -r requirements.txt)
Provide "Start AllTalk Server" button that launches the server process
Auto-detect when server is ready (poll http://127.0.0.1:7851)
Option to auto-start AllTalk when TTS engine is selected

Files affected

src/UI/Features/Video/TextToSpeech/TextToSpeechViewModel.cs - IsEngineInstalled() flow
src/UI/Features/Video/TextToSpeech/DownloadTts/ - new AllTalk installer dialog
src/UI/Logic/Config/SeVideoTextToSpeech.cs - AllTalk install path setting
