CPU usage feature:
- New cpu.rs module: background sampler thread, cross-platform (macOS + Linux)
- Status message byte 1 now carries CPU load (0-100%), matching MikroTik format
- Status format corrected: [type][cpu][00][00][seq:4 LE][bytes:4 LE]
- Client and server exchange CPU in every status message
- Display format: "cpu: 40%/12%" (local/remote), "!" warning if > 70%
- Both client and server show local + remote CPU per interval
- Syslog TEST_END could include CPU averages (future enhancement)
Removed btest-opensource submodule — we've fully reimplemented the protocol
with EC-SRP5 auth, multi-connection, IPv6, syslog, CSV, and CPU monitoring.
The original project is still credited in LICENSE and README.
58 tests, all passing.

New features:
- --syslog <address:port> sends structured events to remote syslog (RFC 5424 UDP)
Events: AUTH_SUCCESS, AUTH_FAILURE, TEST_START, TEST_END, TEST_RESULT
- EC-SRP5 authentication for both client and server modes
- TCP multi-connection support (session tokens, all 3 directions)
Bug fixes since v0.2.0:
- EC-SRP5 server: fixed gamma parity (was 50% auth failure rate)
- EC-SRP5 server: use lift_x not redp1 for verification
- TCP send direction: server sends 12-byte status messages to client
- TCP both direction: TX loop injects status between data packets
- TCP data: send all zeros (no 0x07 header that MikroTik rejected)
- TCP disconnect detection: running flag set on EOF
- UDP multi-connection: unconnected socket accepts all source ports

Full reimplementation of the MikroTik Bandwidth Test protocol:
- Server mode: accepts connections from MikroTik devices on port 2000
- Client mode: connects to MikroTik btest servers
- TCP and UDP protocols with bidirectional support
- MD5 challenge-response authentication
- Dynamic speed adjustment (1.5x algorithm)
- Status exchange matching original C pselect() behavior
- Docker support with multi-stage build
Tested against MikroTik RouterOS achieving:
- 1.05 Gbps server RX (single connection)
- 530 Mbps client TCP download
- 840 Mbps client TCP upload
- 433 Mbps client UDP download
