feat: add type safe entity names file

[gonpombo8]

Entity Names Type Generation

Description

This PR introduces a new feature to automatically generate TypeScript definitions for entity names in the scene. It simplifies referencing scene entities by name with full type safety and IDE autocompletion support.

Implementation Details

• Added a new function generateEntityNamesType to create a TypeScript file with string literal types for entity names
• Automatically generates this file whenever the scene composite is saved
• Creates both a string literal union type and a constant object for better developer experience
• Entity names are properly sanitized for valid TypeScript identifiers

Benefits

• Type safety when referencing entities by name in code
• Autocomplete support in IDE for all named entities in the scene
• Prevents runtime errors from typos in entity name strings
• Makes refactoring entity names easier as TypeScript will catch all references

Example Usage

import { EntityNames } from '../assets/scene/entity-names'

// Auto-completion support via constant object
const GroundBoedoOrNull = engine.getEntityOrNullByName(EntityNames.Ground_Boedo1) 
const GroundBoedo = engine.getEntityByName<EntityNames>(EntityNames.Ground_Boedo1)
console.log(GroundBoedo)

This implementation helps reduce runtime errors and improves the developer experience when working with named entities in Decentraland scenes.
