## Description
- Introduces a new engine command execution model that replaces the
previous approach of mapping `EngineComponentKey` to React components.
Instead, engine commands are now mounted headlessly via
`HeadlessEngineCommandMountRoot`, with their execution context populated
synchronously before mounting.
- Creates new headless command components
- Moves error handling from the SDK layer to the host app by wrapping
all mounted commands with a new `CommandMenuItemErrorBoundary`
The new flow works as follows:
- When a command menu item with an `engineComponentKey` is clicked,
`useCommandMenuItemFrontComponentCommands` calls
`useMountEngineCommand`, which synchronously reads the current context
store (object metadata, selected records, filters, view ID, etc.) and
writes a `MountedEngineCommandContext` into
`mountedEngineCommandsState`.
- The command is then mounted into `mountedEngineCommandsState`, which
triggers `HeadlessEngineCommandMountRoot` to render the corresponding
headless component from `ENGINE_COMPONENT_KEY_HEADLESS_COMPONENT_MAP`,
wrapped in `CommandMenuItemErrorBoundary`,
`ContextStoreComponentInstanceContext.Provider`, and
`EngineCommandComponentInstanceContext.Provider`.
- Each command component reads its execution context and delegates to
one of the 4 execution patterns: `HeadlessEngineCommandWrapperEffect`
(simple actions), `HeadlessConfirmationModalEngineCommandEffect`
(destructive actions needing confirmation),
`HeadlessNavigateEngineCommand` (GO_TO_* commands), or
`HeadlessOpenSidePanelPageEngineCommand` (SEARCH_RECORDS, ASK_AI,
VIEW_PREVIOUS_AI_CHATS).
- After execution, the command self-unmounts via
`useUnmountEngineCommand`, which removes the entry from
`mountedEngineCommandsState` and stops rendering the component.
actions are being renamed to command menu item, they will be migrated to
server and will be served as headless front components

## 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)
