## PR description
- Adds `enqueueSnackbar` to the front component host communication API,
allowing front components to display snack bar notifications (success,
error, info, warning) to the user.
- Introduces `frontComponentId` to the `FrontComponentExecutionContext`
and a `useFrontComponentId` hook, enabling front components to identify
themselves (used for dedupe keys).
- Wires error/success notifications into the `Action`, `ActionLink`, and
`ActionOpenSidePanelPage` SDK components -> actions now catch errors and
display them as snack bars, and `Action` supports an optional
`notifyOnEnd` prop for success feedback.

## Description
- Add `isHeadless` field to `FrontComponent` entity so front components
can run without rendering UI in the command menu
- Introduce headless front component mounting logic:
`HeadlessFrontComponentMountRoot` at the application root,
`useMountHeadlessFrontComponent`, and `useUnmountHeadlessFrontComponent`
hooks to mount/unmount headless components
- Expand the SDK with new action components (`Action`, `ActionLink`,
`ActionOpenSidePanelPage`) and host communication functions
(`openSidePanelPage`, `unmountFrontComponent`)
- Move `CommandMenuPages` type to twenty-shared so the SDK can reference
it for side panel navigation

## 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
