The JIT that runs makepad apps from source: lexer, front end, type checker, lazy borrow checker (Gandalf; `--check-first` opts in), codegen, session and warm/cold caches keyed by compiler stamp, provided crates bound late, startup images, live patching. User-facing name is `makepad run` (binary `makepad`, MAKEPAD_RUN_* env, ~/.makepad-run); libs/relax stays the internal library name. `makepad check` reports rustc-style diagnostics with rustc error codes and checks a whole workspace (`--workspace`). Runs on macOS, Linux, Windows and Android. makepad-remote: one tool schema for apps and the WM (app/1): grabs, captures, traces, frame profiles and tweaks.

// 3.12: adding a Drop impl changes needs_drop(T): every fn that drops a T (here Vec<T>::clear's

|
// drop glue) must be recompiled, so values made before the edit are counted when dropped after it.
|
|
// Each run clears the items the previous run pushed, prints the drop count, and pushes 3 more.
