New Features - Added policy-based memory allocation APIs with capability flags and optional alignment: `memory_alloc_with_policy`, `memory_realloc_with_policy`, `memory_calloc_with_policy`, and `memory_free`. - Switched heap memory reporting to `memory_print_stats`. Bug Fixes - Improved allocation robustness with capability fallback behavior. - Added overflow-safe handling for aligned zero-initialized allocations. - Tightened const-correctness for generated device-tree device arrays. Tests - Added unit tests for default policy, alignment, zero-initialization, realloc preservation, freeing, and memory stats reporting.
