Finalize the Effect View rename and refresh docs, examples, and tooling (#59)

## Summary

- Rename `effect-fc-next` to `effect-view` and update package metadata, internal symbols, imports, and repository references.
- Promote the Effect 4 example to `packages/example` and move the legacy Effect 3 example to `packages/effect-fc-example`.
- Add `effect-view` to the npm publishing workflow.
- Update the Vite Fast Refresh plugin for `effect-view` and rename `effectViewPlugin()` to `effectView()`.
- Upgrade Effect, React, TypeScript, build tooling, and related dependencies.
- Refresh the documentation and homepage.

## Documentation

- Add a dedicated Async guide covering:
  - Suspense fallbacks
  - Hook ordering
  - Memoization
  - Structural prop equality
- Clarify synchronous and asynchronous component behavior.
- Document runner scope and service requirements.
- Explain stable construction of Query, Mutation, and Form instances.
- Expand focused Lens and Form examples, including curried focus helpers.
- Document the optional `@effect/platform-browser` dependency for window-focus query refresh.
- Improve the Forms guide structure and examples.
- Fix responsive homepage headline wrapping and update homepage copy.

## Notable API changes
