loop-uh 3f8f8f27e7 Extract mtproxy module with unified retry authority
Move MTProxy policy engine from tgnet/ to self-contained jni/mtproxy/ module. Consolidate reconnect hold computation into single MtProxyRetryAuthority owner (was split across Connection, ConnectionSocket, endpoint policy, and probe coordinator, causing hold misalignment bugs). Add MtProxyTerminalDiagnostic module with host tests for pre-I/O verdict preservation (fixes 02.07/30.06 clobber livelocks). Auto-generate phase classification (isPreIoTerminalVerdict, needsReconnectBackoff, isObservationFacadePhase, isLocalSchedulerTimeout) from single Python contract into both C++ and Java to eliminate parallel maintenance. Pass native hold (coordinator terminal hold + endpoint cooldown) via JNI to Java so reconnect timer and health store use THE clock, not re-derived ones. Optimize log flushing: batch debug lines, flush errors immediately. Add module boundary guard, host build system (MSVC), and unit tests for retry logic and terminal diagnostic derivation.
