Bin compat: use Platform.getFullExecutablePath instead of CommandLine.arguments.first for ProcessInfo.processName.

iCharlesHu · iCharlesHu · commit 37c8705674b7 · 2025-07-09T11:24:02.000-07:00
The original NSProcessInfo implementation calls _CFProcessPath for processName, which Platform.getFullExecutablePath internally calls. We should maintain the same behavior for binary compatibility.
