russell@unturf.com ff2ef382c7 gc diagnostics: per-tier heap pressure surfaced in repl tabbar ... Step 1 of the GC effort. Each tier loader now exposes heapStats(): - asm-wasm — lumbda_heap_used / lumbda_heap_total wat exports - c-wasm — emscripten linear memory size (no free path right now, so used = total; documented in the loader) - python — pyodide module linear memory size; CPython GC cycles this naturally Worker handles a "heap" message kind that round-trips the active tab's loaded tiers; repl tabbar shows a compact "py 12M · c 32M · asm 4M" strip next to the buttons. Polls every 2s. Doesn't solve the leak — just makes pressure visible so the user knows when to use "reboot tier". Real GC (Cheney over the WAT bump allocator, Boehm-em or custom mark-sweep for c-wasm) coming next.		2026-06-14 17:32:48 -04:00
