refactor(clash): 按流量特征重构分流配置

代理组重构:
- 流媒体: YouTube/Netflix/Disney+/Spotify/Twitch...
- 大文件下载: GitHub/Docker/npm/PyPI/HuggingFace/Steam (不含byWave)
- 社交通讯: Discord/Twitter/Reddit/Telegram/Facebook...
- 日系站点: DLsite/Pixiv/DMM/Niconico/Booth/Fantia...
- Exhentai: 独立组 (避开日本节点)
- PT站点: 网页+Tracker走代理, BT下载走直连
- Apple/Google/Microsoft: 独立平台组
- AI/Tailscale: 固定组

新增规则集: streaming, social, jp-content, tailscale
修复: rule-provider path冲突, Gemini规则重复
优化: applications规则移到pt-custom之后确保PT tracker走代理
