Adds driver for the Texas Instruments INA219BIDR — a popular 26V, 12-bit I2C current and power monitor used in battery management, solar chargers, and embedded power monitoring. - LCSC part C2155799 with auto-generated KiCad footprint/symbol - Configurable shunt resistor with parametric max_current assertion - Inline bridge trait for drop-in power path monitoring - 4 selectable I2C addresses (0x40/0x41/0x44/0x45) via A0/A1 pins - Includes decoupling cap and I2C pull-ups

Summary
Adds a driver package for the Texas Instruments INA219BIDR — a widely used 26V, 12-bit I²C current and power monitor.

The INA219 is one of the most popular current/power monitoring ICs in the maker and embedded community (Adafruit, SparkFun, Arduino, RPi projects) and was missing from the atopile package registry. This fills that gap alongside the existing
ti-ina228(higher-end 20-bit variant).Test plan
