Admin b22a714840 makepad run: the Rust JIT (libs/relax) and makepad-remote
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.
