configuredElectronFlags() inlined HERMES_HOME normalization, so it missed
the two cases resolveDesktopHermesHome() handles: HERMES_DATA_DIR_SUFFIX
channel installs and profiles/-rooted HERMES_HOME values. Both read
config.yaml from a different home than main.ts does, silently dropping
desktop.electron_flags on the relaunch. Use the shared resolver and cover
both shapes with bundle-entry regression tests.
