Add native tests, ASCOM Alpaca API, and README

Native test suite (61 tests, 5 suites) with thin mock layer for
Arduino/FreeRTOS/esp_timer enabling host-side testing without hardware.

ASCOM Alpaca REST API on port 32323 with UDP discovery, implementing
Telescope v3 interface for N.I.N.A., PHD2, and compatible software.
Follows existing ST4WiFi conditional compilation pattern.

README documents wiring, all three protocols (serial, WebSocket, Alpaca),
pin/rate configuration, and build instructions.

Harden safety-critical paths from Hamilton review

- Fix lock hierarchy: stopAll() cancels pulse before touching axes
- Add configASSERT bounds checks on axis index in move/pulseGuide
- Enforce ST4Pulse singleton with configASSERT
- Check esp_timer_start_once return, rollback hardware on failure
- Validate SYNC coordinates (reject garbage → silent 0.0)
- Discard truncated serial commands on buffer overflow
- Guard WiFi update()/broadcastState() against null ws_ pointer
- Report connection errors to WebSocket clients on move/pulse
- Remove redundant Serial.begin() from pulse_guide example

ESP32 ST-4 autoguider library with thread-safe pulse guiding

Port of arduino-st4 (Kevin Ferrare) to ESP32/PlatformIO with:
- FreeRTOS mutex protection at every layer (Pin, Axis, Pulse, Controller)
- Hardware timer pulse guiding with ISR-safe deferred stop pattern
- Backward-compatible serial protocol (57600 baud, #-terminated)
- Extended commands: PULSE, POS?, SYNC, STATUS?, VERSION?
- Optional WiFi/WebSocket control (gated by ST4_WIFI_ENABLED)
- Dead-reckoning position tracker using esp_timer microsecond precision

All 4 examples build clean against esp32dev target.
