Félix Malfait 2803292521 feat: add Metadata Builder agent for data model management (#16350)
## Summary

This PR adds a new **Metadata Builder** AI agent that specializes in
managing the workspace data model (creating objects, adding fields,
etc.).

## Changes

### New Files
- `data-model-manager-role.ts` - New standard role with `DATA_MODEL`
permission flag
- `metadata-builder-agent.ts` - New standard agent for data model
management

### Modified Files
- **ChatToolsProviderService**: Refactored to consolidate all
permission-based tools into a single `getChatTools()` method. Now
injects both workflow tools and metadata tools based on permissions.
- **AgentChatRoutingService**: Updated to use the new consolidated
`getChatTools()` method
- **AiChatModule**: Added imports for `ObjectMetadataModule` and
`FieldMetadataModule`
- **Router system prompt**: Added metadata-builder agent selection rules
with clear distinction between schema operations vs data operations
- **Metadata tools factories**: Improved error messages to show detailed
validation errors instead of generic messages

### Refactoring
- Renamed `index.ts` files to `standard-agent-definitions.ts` and
`standard-role-definitions.ts` to follow naming conventions
- Renamed exports from `standardAgentDefinitions` to
`STANDARD_AGENT_DEFINITIONS` (SCREAMING_SNAKE_CASE)

## Key Features

1. **Metadata Builder Agent** can:
   - Create new custom objects
   - Add fields to existing objects
   - Update object and field properties
   - Create relations between objects

2. **Permission-based tool injection**: Tools are automatically injected
based on the `DATA_MODEL` permission flag

3. **Improved routing**: The router now correctly distinguishes between:
   - "Create an object called Project" → metadata-builder (schema)
   - "Create a company called Acme" → data-manipulator (data)

4. **Better error messages**: Validation errors now show detailed
messages like:
   ```
   Validation errors:
   [objectMetadata] Name must be in camelCase format
   [objectMetadata] Label is required
   ```

Does the world need another CRM?

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
