* Fix `cost` SIGSEGV on Linux by gating Bundle.allBundles to macOS
isRunningTests falls back to Bundle.allBundles to detect loaded .xctest
bundles. On Linux (swift-corelibs-foundation) Bundle.allBundles crashes in
_CFIsSwift (via CFBundleGetAllBundles -> CFArrayGetCount), so `codexbar cost`
segfaults before producing output. On Linux, detect the test process from the
main executable path instead: SwiftPM builds test executables with a `.xctest`
suffix, so the intent survives without enumerating bundles. macOS behavior is
unchanged.
Fixes#3058
* Fix remaining Bundle.allBundles fallback in OpenCodexUsage on Linux
