**Key points:**

- **`twenty-front`** depends on the renderer, **not** on `twenty-sdk`
directly (for rendering)
- **`twenty-front-component-renderer`** depends on `twenty-sdk` for
**types only** (function signatures, `FrontComponentExecutionContext`).
The runtime bridge (`frontComponentHostCommunicationApi`) is shared via
`globalThis` keys, not module imports
- **`twenty-sdk`** has no dependency on the renderer — clean one-way
dependency
- The renderer owns all remote-dom infrastructure (element schemas,
event mappings, custom element tags) that was previously leaking through
the SDK's public API
- The SDK's `./build` entry point was removed entirely (unused)
