Adds the infrastructure for a coherent client-side error story: - `lib/errors.ts`: canonical ApiError + QuotaExceededError, `toUserMessage` (friendly strings for ApiError/ZodError/network errors, strips Electron IPC message prefixes), `logError` (expected), `reportError` (unexpected). - `lib/query-client.ts`: QueryClient factory with sane retry defaults (no retry on 4xx except 408/429, 2 retries otherwise; 0 mutation retries), `QueryCache` onError logs + opts in via `meta.toastOnError`, and `MutationCache` onError toasts `toUserMessage(err)` by default with `meta.suppressToast` as the opt-out. - `components/app-error-boundary.tsx` + `error-fallback.tsx`: two boundaries (top-level outside the router, route-level inside) with a Card-based fallback offering 'Go home' + 'Try again'. Route boundary resets on pathname change and clears React Query error cache on retry. - `main/ipc-utils.ts` + main.ts migration: `safeHandle` wraps ipcMain.handle so main-process failures log with full stack and surface a sanitized message to the renderer. `link:fetch-metadata` keeps its null contract but now logs. - `useCreateParticle` opts out of the global toast (compose-overlay renders its own quota UX) so nothing double-toasts. Render crashes now have a recovery UI, every mutation gets a free error toast, and silent-catch cleanup + Sentry land in follow-up PRs.
