Fix Sherpa local ASR state sync

[weikeyi]

User description

摘要

• 在设置变更和 Windows 启动时，将持久化的 active ASR provider 同步到后端运行时的 credentials vault，避免前端偏好与实际听写 provider 状态不一致。
• 让 Sherpa ONNX catalog/download 状态与已解压的 release archive 资源保持一致，包括 Qwen3 tokenizer/ 目录校验和 downloadedBytes 统计。
• 更新前端对 Sherpa ONNX provider 的识别：Overview / Settings 可正确显示 sherpa-onnx-local，并且 Sherpa 模型存在部分下载或已解压资源时允许删除。

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Stale Sync The vault sync now only runs when active_asr_provider changes, so saving other settings while the provider stays the same will not repair a drifted or cleared vault entry. In that case the UI preferences can remain saved while the runtime still uses the old provider until the next startup sync. let active_asr_provider_changed = previous.active_asr_provider != prefs.active_asr_provider; let active_asr_provider = prefs.active_asr_provider.clone(); coord.write_settings(prefs)?; if active_asr_provider_changed { coord.sync_active_asr_provider(&active_asr_provider)?; }
