- Add static memory pool implementation (se050_mem_pool.c/h) - Replace all malloc/calloc with pool allocations - Replace all free with pool deallocations - Remove strdup usage (use fixed-size buffer instead) - Update I2C HAL to use fixed-size dev_path array - All 24 tests pass with static memory only Suitable for embedded environments (u-boot, ESP32) without heap.
