- 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)
