Shelley Vohr	76331f0564	refactor: replace `CHILD_PLUGIN` with `CHILD_EMBEDDER_FIRST` on macOS (#50278 ) refactor: replace CHILD_PLUGIN with CHILD_EMBEDDER_FIRST on macOS Chromium removed upstream support for child plugin processes without library validation in https://crbug.com/461717105, which we patched back via feat_restore_macos_child_plugin_process.patch. Chromium's CHILD_EMBEDDER_FIRST mechanism already provides the right extensibility point for this: values > CHILD_EMBEDDER_FIRST are reserved for embedders and resolved via ContentBrowserClient::GetChildProcessSuffix(). Chrome itself uses this pattern for its Alerts helper process. This commit replaces the Chromium patch with an Electron-native implementation.	2026-03-17 14:41:15 -04:00
