- refactor(ProviderList): use shared base_url helpers
- refactor(App): reuse shared base_url helpers for VS Code sync
- fix(auto-sync): global shared VS Code auto-apply state (localStorage + event broadcast)
- feat(tray): auto-apply to VS Code on Codex provider-switched when enabled
- behavior: manual Apply enables auto-sync; manual Remove disables; official providers clear managed keys only
- chore(typecheck): pass pnpm typecheck
