* fix(rate-limits): spawn the Codex usage probe off the main thread On Windows, creating a cold standalone codex.exe can spend seconds in code integrity checks on the calling thread. The usage probe runs on window focus, so that froze the UI. The probe's child is now created and piped on a worker thread and proxied back to the main thread. Fixes #27362 * refactor(rate-limits): type the worker's children through @orca/process-host * fix(rate-limits): kill an orphaned Codex probe by pid when its worker dies Once the worker thread that owns the probe's child is gone, kill() can no longer reach the child through it. The proxy now falls back to a pid-addressed kill; the Codex probe uses the app-server tree kill so a node launcher's codex.exe child goes too, while SIGTERM stays a graceful root signal. * refactor(build): move the main build's entry map out of electron.vite.config.ts The new worker entry pushed electron.vite.config.ts past the 300-line limit. The Rollup input map for the main build now lives in its own module. * refactor(rate-limits): drop the orphan pid kill and trim the worker child-process stand-in A worker thread's death closes its children's pipes, so an abandoned Codex probe already gets stdin EOF, its graceful stop. The pid-addressed orphan kill was redundant with that and with terminateCodexProbeChild's own gated Windows tree kill. Its hard kill also bypassed the tree-kill gate's recycled-pid refusal by turning the handle-addressed fallback into a pid kill. - Remove orphan-pid-kill, killOrphanedCodexProbe, the injected killOrphan, and the orphaned flag. kill() now reports false once a child is no longer tracked. - Process-creation failure is one 'spawn-error' event that the stand-in expands into error/exit/close, replacing the duplicated triple and the exported exit code. Stdin errors arrive as child errors, as the probe already treated them. - Fold both suites into one over a real MessageChannel and real children. Add a real-worker test showing that terminating or crashing the worker lets the child exit on stdin EOF. * test(rate-limits): run the worker child-process suite under Node The suite asserts Node behavior that Electron main relies on: a failed spawn closes with a null signal, and a dead worker thread closes its children's pipes. Bun reports an undefined signal and, on Linux, leaves the pipes open, so the Bun lane failed on runtime differences, not on the product code. * test(rate-limits): count a reaped-by-nobody zombie as an exited child On Linux and macOS a child whose worker thread died gets stdin EOF and exits, but libuv reaps a child only through the handle on the loop that spawned it. Once that loop is gone, nothing waits on the pid, so it stays a zombie and kill(pid, 0) still succeeds. The real-worker tests now treat a zombie as exited, and still require the child's EOF marker. --------- Co-authored-by: Orca Worker <orca-worker@localhost>
