Wraps malloc/calloc/realloc/free (and heap_caps_* variants) via the linker, records every event into a PSRAM ring with optional call backtraces, and streams the ring as TSV over HTTP (ESPAsyncWebServer) or Serial for a standalone HTML viewer with a heap map and addr2line symbolization. REQUIRES linker --wrap flags (see README) which the Arduino IDE cannot auto-inject.
