swaits 7dd717a887 fix(clients/rust): harden client resilience for v0.1.0 release

- Track serial timeout in field instead of returning hardcoded 2s
- Always restore timeout in drain_rx, even on read errors
- Handle EINTR/Interrupted in read_frame (retry instead of error)
- Use connect_timeout for TCP mux (no more 2-min hangs)
- Set write timeout on mux sockets (unix + tcp)
- Log unexpected unsolicited frames in recv via tracing::warn
- Add unix socket timeout test for WouldBlock handling
- Add CHANGELOG.md, remove resolved CLAUDE_TODO.md

Changelog

0.1.0 — 2026-04-06

Initial release.

Features

High-level Client<T> with send/recv and command helpers (ping, set_config, start_rx, stop_rx, transmit, get_config, get_mac, display_on, display_off)
COBS wire framing via ucobs (matches firmware implementation)
Auto-detection connection: TCP mux, Unix socket mux, direct USB serial
Bounded RX packet buffering (256 packets, FIFO eviction)
FrameReader accumulator for streaming byte sources
USB device discovery by VID:PID with blocking wait

Resilience

Cross-platform timeout handling: TimedOut (Windows) and WouldBlock (Linux/macOS) both treated as clean timeouts in read_frame
EINTR/Interrupted signals retried automatically in read_frame
drain_rx always restores the original timeout, even on I/O errors
TCP mux connections use connect_timeout (bounded by caller's timeout)
Mux sockets set both read and write timeouts
SerialTransport tracks timeout accurately for save/restore
Unexpected unsolicited frames logged via tracing::warn instead of silently discarded
