hailin 549b21f298 fix(message-router): prevent subscription race condition on gRPC reconnect
When a party re-subscribes (e.g., Android reconnects), the old gRPC stream's
defer Unsubscribe() was accidentally removing the NEW subscription from the
subscribers map, causing the party to miss session_started events.

Fix:
- Subscribe() now returns the channel to the caller
- Unsubscribe() now takes the channel and only removes if it matches
- This prevents older streams from removing newer subscriptions

hailin e2451874ea fix(android): add logging for session event subscription debugging
- Add warning log when parties miss session event broadcast (message-router)
- Add logging for subscribeSessionEvents to detect null asyncStub
- Add sessionStatusPollingJob field for future fallback polling mechanism

This helps diagnose why Android parties are not receiving session_started events.

hailin 0ca37ee76a feat(mpc-system): 增强连接可靠性和消息去重机制
后端改进:
- SessionEventBroadcaster: 重连时自动关闭旧 channel 防止内存泄漏
- MessageBroker: 重连时关闭旧的 party/session channel
- SubscribeMessages: 订阅时自动发送数据库中的 pending 消息

客户端改进:
- GrpcClient: 添加自动重连机制(指数退避,最多10次)
- GrpcClient: 断开/重连/失败事件通知前端
- TSSHandler: 消息缓冲机制,进程启动前缓存收到的消息
- TSSHandler: 客户端本地消息去重,防止重连后重复处理
- Database: 添加 processed_messages 表和相关操作方法
- Main: Keygen 幂等性保护,防止重复触发
- Main: 会话事件缓存,解决前端订阅时序问题

hailin c52b6aa980 refactor(mpc-system): replace K8s party discovery with Message Router-based discovery
- Add GetRegisteredParties gRPC method to Message Router for party discovery
- Create MessageRouterPartyDiscovery adapter in Session Coordinator
- Remove K8s dependency from Session Coordinator (works in any environment)
- Add party registration to server-party-api on startup
- Fix docker-compose.yml: add MESSAGE_ROUTER_ADDR to session-coordinator

This change implements a fully decentralized party discovery mechanism:
- Parties register themselves to Message Router on startup
- Session Coordinator queries Message Router for available parties
- Works in Docker Compose, K8s, or any deployment environment

hailin 747e4ae8ef refactor(mpc-system): migrate to party-driven architecture with PartyID-based routing
- Remove Address field from PartyEndpoint (parties connect to router themselves)
- Update K8s Discovery to only manage PartyID and Role labels
- Add Party registration and SessionEvent protobuf definitions
- Implement PartyRegistry and SessionEventBroadcaster domain logic
- Add RegisterParty and SubscribeSessionEvents gRPC handlers
- Prepare infrastructure for party-driven MPC coordination

This is the first phase of migrating from coordinator-driven to party-driven
architecture following international MPC system design patterns.
