Add TMP119 I2C temperature sensor driver (Claude_Opus4.6)

New driver WipperSnapper_I2C_Driver_TMP119.h with read-caching pattern,
explicit configuration pinning (continuous mode, 8x averaging), and
registration in WipperSnapper_I2C.h/.cpp.

TMP119 uses the existing Adafruit_TMP117 library (no new deps needed).

Companion Wippersnapper_Components PR needed for component definition:
