## 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
```
