Alexey 6ff29e43d3 Middle-End protocol hardening ...

- Secure framing / hot-path fix: enforced a single length + padding contract across the framing layer. Replaced legacy runtime `len % 4` recovery with strict validation to eliminate undefined behavior paths.

- ME RPC aligned with C reference contract: handshake now includes `flags + sender_pid + peer_pid`. Added negotiated CRC mode (CRC32 / CRC32C) and applied the negotiated mode consistently in read/write paths.

- Sequence fail-fast semantics: immediate connection termination on first sequence mismatch with dedicated counter increment.

- Keepalive reworked to RPC ping/pong: removed raw CBC keepalive frames. Introduced stale ping tracker with proper timeout accounting.

- Route/backpressure observability improvements: increased per-connection route queue to 4096. Added `RouteResult` with explicit failure reasons (NoConn, ChannelClosed, QueueFull) and per-reason counters.

- Direct-DC secure mode-gate relaxation: removed TLS/secure conflict in Direct-DC handshake path.
