## Split twenty-sdk build into separate Node and browser targets
The SDK was bundling Node.js code (CLI, SDK API) and browser code (UI
components, front-component renderer) through a single Vite config. This
caused incorrect externalization — Node builtins leaked into browser
bundles and browser-specific chunking logic applied to CLI output.
This PR splits the build into `vite.config.node.ts` and
`vite.config.browser.ts` so each target gets the right externals and
output format.
Also includes a few housekeeping renames:
- `front-component` export path → `front-component-renderer` (matches
what it actually is)
- `front-component-common` merged into `front-component-api` (was a
needless extra module)
## PR Description
This PR:
- Introduces a `FrontComponentHostCommunicationApi`, which allows us to
pass functions to be executed from the worker
- Exposes a navigate function from the host to the front component
remote workers, enabling SDK components to trigger in-app navigation
- Gets rid of `useSyncExternalStore` and makes the execution context
reactive without it
- Refactors and improves the `esbuild` plugin system
