Move all startup output (DC pings, proxy links) from println!() to
info!() for consistent tracing format. Add reload::Layer so startup
messages stay visible even in silent mode.
- Added fire-and-forget ignition via `--init` CLI command:
- New `mod cli;` module handling installation logic
- Extended `parse_cli()` to process `--init` flag (runs synchronously before tokio runtime)
- Expanded `--help` output with installation options
- `--init` command functionality:
- Generates random secret if not provided via `--secret`
- Creates `/etc/telemt/config.toml` from template with user-provided or default parameters (`--port`, `--domain`, `--user`, `--config-dir`)
- Creates hardened systemd unit `/etc/systemd/system/telemt.service` with security features:
- `NoNewPrivileges=true`
- `ProtectSystem=strict`
- `PrivateTmp=true`
- Runs `systemctl enable --now telemt.service`
- Outputs `tg://` proxy links for the running service
- Implementation approach:
- `--init` handled at the very start of `main()` before any async context
- Uses blocking operations throughout (file I/O, `std::process::Command` for systemctl)
- IP detection for tg:// links performed via blocking HTTP request
- Command exits after installation without entering normal proxy runtime
- New CLI parameters for installation:
- `--port` - listening port (default: 443)
- `--domain` - TLS domain (default: auto-detected)
- `--secret` - custom secret (default: randomly generated)
- `--user` - systemd service user (default: telemt)
- `--config-dir` - configuration directory (default: /etc/telemt)

- Per-DC latency tracking in UpstreamState (array of 5 EMA instances, one per DC):
- Added `dc_latency: [LatencyEma; 5]` – per‑DC tracking instead of a single global EMA
- `effective_latency(dc_idx)` – returns DC‑specific latency, falls back to average if unavailable
- `select_upstream(dc_idx)` – now performs latency‑weighted selection: effective_weight = config_weight × (1000 / latency_ms)
- Example: two upstreams with equal config weight but latencies of 50ms and 200ms → selection probabilities become 80% / 20%
- `connect(target, dc_idx)` – extended signature, dc_idx used for upstream selection and per‑DC RTT recording
- All ping/health‑check operations now record RTT into `dc_latency[dc_zero_index]`
- `upstream_manager.connect(dc_addr)` changed to `upstream_manager.connect(dc_addr, Some(success.dc_idx))` – DC index now participates in upstream selection and per‑DC RTT logging
- `client.rs` – passes dc_idx when connecting to Telegram
- Summary: Upstream selection now accounts for per‑DC latency using the formula weight × (1000/ms). With multiple upstreams (e.g., direct + socks5), traffic automatically flows to the faster route for each specific DC. With a single upstream, the data is used for monitoring without affecting routing.

- Fix: LruCache::get type ambiguity in stats/mod.rs
- Changed `self.cache.get(&key.into())` to `self.cache.get(key)` (key is already &[u8], resolved via Box<[u8]>: Borrow<[u8]>)
- Changed `self.cache.peek(&key)` / `.pop(&key)` to `.peek(key.as_ref())` / `.pop(key.as_ref())` (explicit &[u8] instead of &Box<[u8]>)
- Startup DC ping with RTT display and improved health-check (all DCs, RTT tracking, EMA latency, 30s interval):
- Implemented `LatencyEma` – exponential moving average (α=0.3) for RTT
- `connect()` – measures RTT of each real connection and updates EMA
- `ping_all_dcs()` – pings all 5 DCs via each upstream, returns `Vec<StartupPingResult>` with RTT or error
- `run_health_checks(prefer_ipv6)` – accepts IPv6 preference parameter, rotates DC between cycles (DC1→DC2→...→DC5→DC1...), interval reduced to 30s from 60s, failed checks now mark upstream as unhealthy after 3 consecutive fails
- `DcPingResult` / `StartupPingResult` – public structures for display
- DC Ping at startup: calls `upstream_manager.ping_all_dcs()` before accept loop, outputs table via `println!` (always visible)
- Health checks with `prefer_ipv6`: `run_health_checks(prefer_ipv6)` receives the parameter
- Exported `StartupPingResult` and `DcPingResult`
- Summary: Startup DC ping with RTT, rotational health-check with EMA latency tracking, 30-second interval, correct unhealthy marking after 3 fails.

- 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)
