feat(tak): phase 4 hardening

[krital]

Summary

• harden reconnect behavior with bounded exponential backoff and optional jitter
• add config controls for reconnect policy (reconnect_max_delay_ms, reconnect_backoff_multiplier, reconnect_jitter_ms)
• make outbound more resilient by treating stream and multicast egress as independent best-effort paths
• harden TCP/TLS connection setup with explicit connect timeout, keepalive/tcpNoDelay, and TLS handshake failure diagnostics
• enforce multicast ingress payload ceiling against configured max_payload_bytes

Validation

• JAVA_HOME=$HOME/.sdkman/candidates/java/21.0.9-zulu mvn -q -Dtest=io.mapsmessaging.network.protocol.impl.tak.TakExtensionTest,io.mapsmessaging.network.protocol.impl.tak.codec.CotXmlCodecTest,io.mapsmessaging.network.protocol.impl.tak.codec.TakProtobufCodecTest,io.mapsmessaging.network.protocol.impl.tak.framing.TakStreamFramerTest,io.mapsmessaging.network.protocol.impl.tak.framing.TakStreamFramerXmlTest test
• JAVA_HOME=$HOME/.sdkman/candidates/java/21.0.9-zulu mvn -q -Dmaven.test.skip=true package
