Migrate the FSP end-to-end session subsystem into src/proto/fsp/ following the established sans-IO shape, and retire the src/protocol grab-bag now that FSP was its last occupant. Relocate the FSP session wire (node/session_wire.rs plus the FSP message types from protocol/session.rs) into proto/fsp/wire.rs. Hoist the pure decision logic into proto/fsp/core.rs over plain-data SessionSnapshots returning an ordered FspAction list the shell drives: session-rekey policy, msg3-resend classification, post-decrypt epoch reaction, setup/dual-init tie-break, coords/path-MTU emit-policy, bounded pending-queue, and IPv6 ECN. The crypto-owning SessionEntry stays shell-side in node/session.rs (matching the FMP ActivePeer pattern); proto/fsp is wire + core + limits only, with no proto->noise dependency and no crypto. Move the coords helpers to proto/stp/ (they serialize TreeCoordinate), and split SessionMessageType: the encrypted-inner 0x10-0x1F variants stay in proto/fsp/wire.rs while the 0x20-0x2F routing signals become a new RoutingSignalType in proto/routing/wire.rs. Migrate the session-MMP shell adapter, which continues to drive proto/mmp/. Retire src/protocol: LinkMessageType and SessionDatagram move to a new shared proto/link.rs, ProtocolError becomes proto::Error (relocated verbatim), the deprecated MessageType alias and the unimported PROTOCOL_VERSION are dropped, and src/protocol/ is deleted along with its lib.rs module declaration. Behavior-neutral: wire bytes unchanged, oracle tests pass unedited except mod-path relocation; adds rekey/epoch characterization tests and pure poll/emit-policy core tests.
