Reorganize the MMP subsystem, behavior unchanged throughout: - Restore the pre-migration role split: move SenderState into sender.rs, ReceiverState (with its GapTracker helper) into receiver.rs, MmpMetrics and RrLog into metrics.rs, and PathMtuState into path_mtu.rs, leaving the Mmp aggregate plus the peer/session state in state.rs (1339 to 196 lines). Home the module constants in a new limits.rs and re-export them at the same paths. Pure code-motion with module rewiring; visibility unchanged. - Dissolve the 97-line src/mmp shell, which held only MmpConfig and the monotonic mono_ms() clock: move MmpConfig into config/node.rs (re-exported as crate::config::MmpConfig), move mono_ms() into a new top-level src/time.rs shell time seam, repoint all callers, and delete src/mmp/. Also correct stale src/mmp/ doc-comment path labels to proto/mmp/ where they name the protocol primitives.
