Feature/business ontology cdm support (Fixes #109)

[ZAK1504]

feat: Add Business Ontology Layer with Microsoft CDM support

Overview

Implements a Business Ontology Layer that enables mapping semantic models to Microsoft Common Data Model (CDM) entities.

Key Features

• CDM Entity & Attribute Models: Pydantic-based data validation
• Built-in CDM Catalogs: Core, Sales, and Service catalogs with 8 entities
• Business Ontology: Domain organization (CUSTOMER, SALES, FINANCE, etc.)
• Ontology Mapper: Entity and attribute-level semantic-to-CDM mappings
• Persistence: Save/load JSON for ontologies and mappings
• Query & Analysis: Gap detection, validation, and reporting

Implementation

• Core Modules (1,700+ lines): entities.py, catalog.py, ontology.py, mapper.py
• Test Suite: 97 tests (100% passing)
• Examples: 3 real-world scenarios (business, healthcare, financial)
• Performance: 408K queries/second throughput
• Platform: Windows-compatible with UTF-8 encoding

Testing

pytest tests/cdm/ -v
# 97 passed in 5.79s

Usage Example

from intugle import BusinessOntology, CDMCatalog, OntologyMapper, SemanticModel

# Load CDM catalog
catalog = CDMCatalog.load_builtin('cdm_core')

# Create business ontology
ontology = BusinessOntology(name='My Ontology')
ontology.add_domain('CustomerDomain', DomainType.CUSTOMER)
ontology.add_concept('Customer', 'CustomerDomain', cdm_entity='Contact')

# Map semantic model to CDM
mapper = OntologyMapper(ontology, catalog)
mapper.map_entity('customer', 'Customer')
