Upgrade Electron candidate to TypeScript 7.0.2

 ### Changed
 
+- Upgrade the Electron candidate's TypeScript checker from 6.0.3 to the native
+  7.0.2 compiler. Keep the existing typecheck, test and build commands.
 - Record synthetic Claude and Codex source-scanner timings alongside the Swift
   baseline. Counts and cache transitions pass; packaged-app performance, idle
   RSS and native GUI acceptance remain open.

 - Side notch chrome is derived per theme in `SideNotchPanelView` by an HSV mix pinned to the popover surface's Rec. 709 relative luminance (`blendTinted`), so every accent renders at the same perceived brightness as the window beside it. The notch bands and hues delegate to the shared `headroomColor`/`MU` scale (80/95 thresholds), and the panel window forces `darkAqua` so those tokens resolve their dark variants on the strip.
 - ADR 0006 replaces fixed alternate cases with a managed account list for Codex and Claude. Generated app IDs, provider, user label, directory and enabled state persist as JSON in UserDefaults Data. Primary keys retain their old form; additional history/archive keys use provider plus generated ID, and schema-1 reports add `account` labels. Rename preserves identity; remove stops metering without deleting provider files. No provider account identity is read for labels.
 - ADR 0010 selects macOS TypeScript/Electron/React with pnpm, Vite+, Tailwind, Vitest and electron-builder. Main owns provider files/keys, native actions and persistence; a separate sandbox-compatible preload exposes sender-validated IPC to React. The candidate keeps JSON/history/archive and known preference formats. Swift remains the oracle and rollback path. No server or remote control layer is added.
+- `package.json` selects TypeScript `~7.0.2`, and `pnpm-lock.yaml` resolves the native compiler and its platform packages to 7.0.2. `pnpm typecheck` still runs `tsc --noEmit`; Vite+ builds the application. The compiler upgrade does not establish native migration acceptance or release readiness.
 - Windows implementation, installers, CI, testing and releases are paused until a test machine is available. The former RN/Tauri Windows-first plan is superseded; shared portable source does not establish Windows support.
 - Candidate checks use synthetic fixtures. Demo/candidate selection isolates preferences, history, caches and Electron state before composition. Live provider/key discovery, updater installation and login-item changes are disabled in demo. `pnpm package:mac` creates a separate candidate with publication disabled, using existing macOS tools.
 - Candidate account visibility rechecks directory presence. Sharing freezes the displayed account key. Pacing-off hides forecasts; notch details reuse window-scoped burn metrics and have a bounded scroller. These contracts have synthetic/static-markup proof; native UI acceptance remains open.
