## 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
steps:
