docs(twitter): add 2061124942968545433 corpus (NOTimothyLottes CART-as-log + GPU-rendered hex)

3-post thread. Replaces the mmap fixed-size log file with a CART file mmapped on CPU with mapped GPU access (no file IO) + background page walker to prevent paging out. Beginning of CART is a grid of 32-bit unsigned values, hex-dumped as the 'log file' to either term or GPU render. Same framework for CPU and GPU debug ('write and it just appears'). Visualized as 4-bit/char hex terminal with hex font.

+no-debugger-debug / console / printf-style - prior evolved to one mmapped fixed-width-height log file with an atomic for multi-thread|process messages - but even that seems too complexy ...

+moving to this >>> CART file is mmapped on CPU with mapped GPU access (no file IO) - background page walker to ensure OS won't page it out - beginning of CART file is a grid of 32-bit unsigned values - hex dumping that as my 'log file' - either to term or GPU render

+hits the easy to debug CPU or GPU stuff in the same framework (simply write and it just appears) - it's always a HEX dump, but can show decimal by pretending it's a 4-bit/character terminal with a hex font :)
