v3.1.3

新功能

• 设置：新增用户可配置代理设置——在设置 > 常规中支持系统代理（默认）、自定义代理（HTTP/HTTPS/SOCKS5 含认证）和直连（绕过所有代理）三种模式（仅桌面端）。包含连接测试按钮及延迟反馈。

修复

• 流水线：当 Whisper 所有片段均被反幻觉过滤器过滤时（如纯音乐音频），显示描述性错误消息而非「未知原因」（Fixes MIOSUB-1M）。
• 编辑器：生成出错时保持顶部操作栏可见，用户可直接重试而无需重新导入字幕。
• Whisper：清理 whisper.cpp JSON 输出中可能导致解析失败的控制字符。
• Whisper：在无 GPU 支持的设备上主动禁用 GPU 以避免初始化时硬崩溃，而非仅依赖崩溃后重试。

安全

• 代理：在日志输出中脱敏代理凭据，并使用结构化 URL 解析进行验证，拒绝格式错误的 URL 和不支持的协议。

Features

• Settings: Add user-configurable proxy settings — support System Proxy (default), Custom Proxy (HTTP/HTTPS/SOCKS5 with auth), and Direct (bypass all proxies) modes in Settings > General (desktop only). Includes connection test button with latency feedback.

Fixes

• Pipeline: Show descriptive error message when all Whisper segments are filtered by anti-hallucination (e.g., music-only audio), instead of "unknown reason" (Fixes MIOSUB-1M).
• Editor: Keep the top action bar visible on generation error so users can retry without re-importing subtitles.
• Whisper: Sanitize control characters in whisper.cpp JSON output that could cause parse failures.
• Whisper: Proactively disable GPU on machines without GPU support to avoid hard crashes during initialization, instead of relying solely on post-crash retry.

Security

• Proxy: Redact proxy credentials in log output and use structured URL parsing for validation, rejecting malformed URLs and unsupported protocols.
