* server/group: refactor group package with shared abstractions and fix concurrency issues Extract common patterns into reusable components: - groupRegistry[G]: generic concurrent map for group lifecycle management - baseGroup: shared plumbing for listener-based groups (TCP, HTTPS, TCPMux) - Listener: unified virtual listener replacing 3 identical implementations Fix concurrency issues: - Stale-pointer race: isCurrent check + errGroupStale + controller retry loops - Worker generation safety: pass realLn and acceptCh as params instead of reading mutable fields - Connection leak: close conn on worker panic recovery path - ABBA deadlock in HTTP UnRegister: consistent lock ordering (group.mu -> registry.mu) - Round-robin overflow in HTTPGroup: use unsigned modulo Add unit tests (17 tests) for registry, listener, and baseGroup. Add TCPMux group load balancing e2e test. * server/group: replace tautological assertion with require.NotPanics * server/group: remove blank line between doc comment and type declaration
