- Add target_os = "android" to CPU sampler (reads /proc/stat like Linux)
- Parse remote CPU from interleaved TCP status messages in BOTH mode
- Add dedicated status reader for TX-only mode (reads server's 12-byte
status messages to get remote CPU and enable speed adaptation)
- Add 3 CPU integration tests: local CPU, TCP BOTH remote, TCP TX-only
Fixes: Android always showing cpu: 0%/0%, TCP remote CPU always 0%
on all platforms (btest-to-btest and btest-to-MikroTik).

- MikroTik encodes CPU as 0x80 | percentage (high bit flag)
- Deserialize: mask with 0x7F and cap at 100
- Serialize: set high bit (0x80 | cpu) to match MikroTik format
- CSV now includes local_cpu_pct and remote_cpu_pct columns
- Both client and server write CPU to CSV

The state is now created in main.rs and passed into run_client, so
when --duration timeout cancels the future, the stats are still
accessible via shared_state.summary(). CSV and syslog now show
real speeds and byte counts.
Verified: TCP loopback shows 32 Gbps in CSV output.

Server now binds on both IPv4 (0.0.0.0) and IPv6 (::) by default.
Uses tokio::select! to accept from whichever listener has a connection.
New flags:
--listen <addr> IPv4 listen address (default: 0.0.0.0, "none" to disable)
--listen6 <addr> IPv6 listen address (default: ::, "none" to disable)
Examples:
btest -s # listen on both v4 and v6
btest -s --listen6 none # IPv4 only
btest -s --listen none # IPv6 only
btest -s --listen 192.168.1.1 # specific IPv4 address

- Rename package to btest-rs (Rust convention for reimplementations)
- MIT license matching the original btest-opensource license
- LICENSE explicitly credits Alex Samorukov's original work
- Comprehensive README with usage, performance numbers, and credits
- CLI --help references the original project

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
