Add Effect v4 support, Fast Refresh tooling, and revamped docs (#56)
## Summary

- Add `effect-fc-next`, a React 19 integration targeting Effect v4 beta.
- Introduce component lifecycles, scoped resources, queries, mutations, forms, lenses, views, and refreshable components.
- Add `@effect-view/vite-plugin` for Vite Fast Refresh support.
- Add an Effect v4 example application covering the new APIs.
- Expand test coverage for both the existing and next-generation packages.
- Replace the starter Docusaurus content with complete Effect View documentation while preserving the Effect v3 docs as a versioned snapshot.
- Update the landing page, navigation, package scripts, and build output.
- Extend CI with linting, tests, package builds, Docker builds, and container publishing.

## Validation

- `bun lint:tsc`
- `bun lint:biome`
- `bun test`
- `bun run build`
- `bun pack`
- Docker image build

@effect-view/vite-plugin

Experimental Vite Fast Refresh support for Effect View components.

import { effectViewPlugin } from "@effect-view/vite-plugin"
import react from "@vitejs/plugin-react"
import { defineConfig } from "vite"

export default defineConfig({
    plugins: [
        effectViewPlugin(),
        react(),
    ],
})

The plugin recognizes Component.make and Component.makeUntraced definitions imported from effect-fc-next. The legacy effect-fc package is not supported. effect-fc-next owns the bundler-neutral refresh cell protocol; this package is the Vite adapter that retains those cells in HMR data. The plugin assigns stable development IDs and self-accepts successfully instrumented modules.

The adapter-facing protocol is exported from effect-fc-next/Refreshable.

Renaming or removing an instrumented View invalidates the module upward instead of leaving a stale mounted descriptor.

React state is retained when the ordered hook signature is unchanged. Adding, removing, or changing a hook call resets the Effect View implementation. Add // @refresh reset to a module to reset its Views on every update.

Current limitations

  • Definitions must be top-level variable, class, or default-export declarations.
  • Hook signature analysis is conservative and based on useX call syntax.
  • Changing a descriptor's trait pipeline during a refresh is not guaranteed to preserve state.
  • Source maps for the injected transform are not generated yet.
