Fixes

Two devices with the same USB ID, only one detected (#128): the detector called usb.core.find(), which returns the first match — users running two coolers with identical VID:PID (e.g. Frozen Warframe 240 + Trofeo Vision 6.86", both 0416:5302) only saw one. Now uses find_all=True and emits a DetectedDevice per physical USB; usb_path (usb:bus:address) disambiguates downstream. Same fix for the macOS detector.
Headless led-mode temp_linked / load_linked had wrong colors (#130): on a headless box the CLI never started a metrics loop, so sensor-linked LED modes ran against a zeroed HardwareMetrics. The CLI composition root now bootstraps SystemService once and seeds every connected device with current metrics before the command runs.

Trcc is now a container — __iter__ yields every connected LCD then LED, __len__ returns total. Call sites can write for device in trcc: and len(trcc) instead of poking _lcd_devices / _led_devices.
