## Add `frontComponent` entity type to SDK
This PR adds a new `frontComponent` entity type at parity with
`serverlessFunction`. Front components are React components that can be
defined and bundled as part of Twenty applications.
### Changes
#### New Entity Type
- Added `FRONT_COMPONENT` to `SyncableEntity` enum
- Front components use `*.front-component.tsx` file naming convention
- CLI command `twenty app:add` now includes `front-component` as an
option
#### SDK Application Layer (`twenty-sdk`)
- Added `defineFrontComponent()` function for defining front component
configurations with validation
- Added `FrontComponentConfig` type for component configuration
- Added `getFrontComponentBaseFile()` template generator for scaffolding
new front components
- Added `loadFrontComponentModule()` to load front component modules and
extract component metadata
#### Shared Types (`twenty-shared`)
- Added `FrontComponentManifest` type with `universalIdentifier`,
`name`, `description`, `componentPath`, and `componentName` fields
- Updated `ApplicationManifest` to include optional `frontComponents`
array
#### Manifest Build System
- Updated `manifest-build.ts` to discover and load
`*.front-component.tsx` files
- Updated `manifest-validate.ts` to validate front components and check
for duplicate IDs
- Updated `manifest-display.ts` to display front component count in
build summary
- Updated `manifest-plugin.ts` to display front component entry points
and watch `.tsx` files
#### Template (`create-twenty-app`)
- New applications now include a sample
`hello-world.front-component.tsx` file
#### Tests
- Added unit tests for `defineFrontComponent()`
- Added unit tests for `getFrontComponentBaseFile()`
## Description
This PR improves the developer experience for the `twenty-sdk` and
`create-twenty-app` packages by reorganizing commands, adding
development tooling, and improving documentation.
## Changes
### twenty-sdk
#### Command Refactoring
- **Renamed `app-watch` → `app-dev`**: Renamed `AppWatchCommand` to
`AppDevCommand` and moved to `app-dev.ts` for consistent naming with the
CLI command `app:dev`
- **Moved `app-add` → `entity-add`**: Relocated entity creation logic
from `app/app-add.ts` to `entity/entity-add.ts` and renamed
`AppAddCommand` to `EntityAddCommand` for better separation of concerns
#### Development Tooling
- **Added `dev` target**: New Nx target `npx nx run twenty-sdk:dev` that
runs the build in watch mode for faster development iteration
### create-twenty-app
#### Improved Scaffolded Project
- **Enhanced base-application README** with:
- Updated Getting Started to recommend `yarn dev` for development
- Added "Available Commands" section listing all available scripts
#### Better Onboarding
- **Improved success message** after app creation with formatted next
