KennethCheng 319eeb44ae feat(gotify): Phase 4 C1 — WebSocket reconnect + 帧解析
- src/gotify/reconnect.rs: ReconnectPolicy 按 §15 退避序列
  1s/2s/4s/8s/16s/30s...record_success() 重置;inline #[cfg(test)]
  3 个 backoff 测试
- src/gotify/websocket.rs: blocking tungstenite 0.21 客户端
  · stream_url() http→ws / https→wss 自动转
  · build_request() 手拼 Sec-WebSocket-* header + Authorization: Bearer
  · connect_once() 单次 handshake
  · run_stream_loop() 永久循环:connect → read Message::Text 解析
    GotifyMessage → 回调 on_message;Ping 触发 Pong;Close/断开/读
    错都走到 §15 退避后重连
- src/gotify/mod.rs: re-export 加 reconnect + websocket 子模块
- Cargo.toml: tungstenite 0.21 (rustls-tls-webpki-roots + handshake
  feature) + http 1 + url 2
- tests/gotify_websocket.rs: 3 个 JSON envelope 解析测试

避坑:
- tungstenite 0.21 的 connect 在 handshake feature 后(默认不带),要
  显式开
- WebSocketConfig 0.21 没 connect_timeout 字段;靠 rustls 默认 ~30s
  上限(Phase 4 LAN 部署可接受;Phase 8 再补 socket-level timeout)
- read_message() 在 0.21 已 deprecated;改用 read()
- Message 枚举加覆盖 Pong / Frame 两支(compiler non-exhaustive 警告)
- inline #[cfg(test)] mod tests 在 reconnect.rs 跑 unit tests(与
  tests/ 集成测试并列)

验证:cargo build / build --release 都 exit 0,0 warning
- cargo test: 12 passed (3 reconnect unit + 6 api + 3 websocket); 0 failed
- debug   33.36 MB, subsystem = WINDOWS_CUI
- release  9.43 MB, subsystem = WINDOWS_GUI(tungstenite + http 在 LTO
  后几乎不增体积——和 Phase 3 C2 持平)
