Detailed Description

Thread-safe façade around se050::Device<HalI2cSe050Comm>.

Typical flow:

BaseI2c& se_i2c = *bus.GetDeviceByAddress(0x48);
Se050Handler se(se_i2c, Se050HandlerConfig{}, nullptr);
if (!se.EnsureInitialized()) { ... }
se050::cmd::VersionInfo v{};
(void)se.GetDevice().GetVersion(&v, se.Config().apdu_timeout_ms);

Parameters

i2c	I²C device whose 7-bit address matches the SE050 (usually 0x48).
config	Timeouts and T=1 tuning.
reset_gpio	Optional SE_RESET / power-style reset line (nullptr if unused).
bus_mutex	Optional shared mutex when multiple devices share the bus.
