Dev/feat roadmap support sync (#62)

This pull request updates the project documentation and configuration to
introduce a detailed integrations roadmap, clarify the status and scope
of framework integrations, and improve coverage reporting and testing
for new packages. The changes also include documentation improvements
for example apps and minor dependency and TypeScript config updates.

**Integrations Roadmap and Documentation:**

* Replaced the informal "Planned Integrations" section in `README.md`
with an executive-style "Integrations Roadmap," providing a snapshot of
integration progress, priorities, and actionable upstream issues. Added
a reference to a new detailed roadmap document.
* Added a comprehensive `docs/roadmap/integrations.md` file detailing
integration progress, checklists, and per-framework status, including
new and upcoming integrations like Electrobun.

**Example App Documentation Improvements:**

* Overhauled `examples/react-nextjs/README.md` and
`examples/react-electron/README.md` to clarify integration scope, usage
instructions, and roadmap links, making them more useful as reference
implementations for framework-specific integration and troubleshooting.

**Testing and Coverage Enhancements:**

* Added new Vitest test and coverage scripts for `react-web` and `tauri`
packages in the root `package.json`, along with corresponding coverage
gates and lanes.
* Set explicit `name` fields in the Vitest config for `react-web` and
`tauri` to support multi-project test reporting.

**Dependency and TypeScript Config Updates:**

* Updated `@vue/tsconfig` to version `^0.9.0` in the Vue PWA example.
* Enabled the `noUncheckedIndexedAccess` TypeScript compiler option in
the Vue PWA example for stricter type safety.

-| -------------------- | -------- | ---------------------------------------------- |
-| Next.js (App Router) | P0       | Official web guide + SSR/client boundary docs |
-| TanStack Start       | P0       | React/web adapter docs + production example    |
-| Astro                | P0       | Client-island starter + worker boot guidance   |
-| SvelteKit            | P1       | Browser-only init reference app                |
-| Nuxt 3               | P1       | Client plugin/module integration path          |
-| Remix / React Router | P1       | Explicit browser init in route patterns        |
-| Tauri                | P1       | WebView runtime + optional relay bridge        |
-| Electron             | P1       | Renderer runtime + optional main-process relay |
-| Capacitor (Ionic)    | P2       | WebView-first runtime hardening                |
-| Flutter              | P2       | Separate SDK/bridge exploration                |
-
-Main blockers to track:
-
-- SSR/client boundaries and hydration order in framework runtimes.
-- Worker lifecycle consistency across browser, edge, and desktop shells.
-- Desktop packaging/process boundaries (Electron/Tauri).
-- Mobile WebView storage consistency and background lifecycle.
-
-Current recommendation:
-
-- Build first-class examples for `Next.js`, `TanStack Start`, and `Astro`.
-- Follow with `SvelteKit`, `Nuxt`, `Remix`, and `Tauri/Electron` runtime guides.
-- Treat `Flutter` as a separate SDK/bridge effort, not a quick wrapper.
-- Keep protocol/API parity first; add adapters only where lifecycle/storage semantics are clear.
+## Integrations Roadmap (Executive View)

+Progress metric uses a weighted checklist (`20%` each):
+
+- Adapter/helper package
+- Reference example
+- Test lane + coverage gate
+- Framework guide (README/docs)
+- CI smoke/hardening
+
+Executive progress values use completed-core-item counting only, so valid values are `0%`, `20%`, `40%`, `60%`, `80%`, `100%`.
