Detailed Description

Bare-metal interrupt handlers, FreeRTOS integration, hardware bus adapters, and critical sections.

Designed specifically for microcontrollers (ARM Cortex-M, ESP32, STM32, RP2040) and real-time operating systems.

Key components:

corium::embedded::IsrEventSink: Safe non-blocking event posting from hardware ISRs.
corium::embedded::FreeRtosIsrSink: FreeRTOS ISR sink managing task unblocking and context switching.
corium::embedded::InterruptLock: Zero-overhead RAII critical section masking across ARM, ESP32, and host.
corium::embedded::SpiAdapter: Hardware SPI frame abstraction and DMA/ISR event adapter.
corium::embedded::I2cAdapter: Hardware I2C transaction frame abstraction and DMA/ISR event adapter.
corium::embedded::CanAdapter / corium::embedded::CanFdAdapter: CAN 2.0B / CAN-FD frame parsing and ISR posting.
corium::embedded::DmaUartBuffer: Lock-free circular DMA buffer for high-throughput UART event streams.
