ME Buffer reuse + Bytes Len over Full + Seq-no over Wrap-add

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.

Zeroize for key + log refactor + fix tests
- Fixed tests that failed to compile due to mismatched generic parameters of HandshakeResult:
  - Changed `HandshakeResult<i32>` to `HandshakeResult<i32, (), ()>`
  - Changed `HandshakeResult::BadClient` to `HandshakeResult::BadClient { reader: (), writer: () }`

- Added Zeroize for all structures holding key material:
  - AesCbc – key and IV are zeroized on drop
  - SecureRandomInner – PRNG output buffer is zeroized on drop; local key copy in constructor is zeroized immediately after being passed to the cipher
  - ObfuscationParams – all four key‑material fields are zeroized on drop
  - HandshakeSuccess – all four key‑material fields are zeroized on drop

- Added protocol‑requirement documentation for legacy hashes (CodeQL suppression) in hash.rs (MD5/SHA‑1)

- Added documentation for zeroize limitations of AesCtr (opaque cipher state) in aes.rs

- Implemented silent‑mode logging and refactored initialization:
  - Added LogLevel enum to config and CLI flags --silent / --log-level
  - Added parse_cli() to handle --silent, --log-level, --help
  - Restructured main.rs initialization order: CLI → config load → determine log level → init tracing
  - Errors before tracing initialization are printed via eprintln!
  - Proxy links (tg://) are printed via println! – always visible regardless of log level
  - Configuration summary and operational messages are logged via info! (suppressed in silent mode)
  - Connection processing errors are lowered to debug! (hidden in silent mode)
  - Warning about default tls_domain moved to main (after tracing init)
