REST API 0.3.0

Added

• Add GET /api/catalog endpoint — faceted search across resources, attributes, operations, and capabilities with paginated results and facet counts
• Support 30+ filter dimensions: type, stability, deprecated, scope, keyword search, sort/order, and type-specific facets for resources (singleton, declaresCap, definesAttrGroups), attributes (dataType, accessType, storage, restart, required, nillable, expressions, sensitive, hasAllowed, unit, hasRelationships, refsCap), and operations (readOnly, runtimeOnly, global, hasParams, hasReturnValue)
• Add sealed Properties interface with ResourceProperties, AttributeProperties, and OperationProperties subtypes for type-specific result fields
• Add singleton field to /api/search results indicating wildcard vs singleton resource status
• Add OpenAPI annotations to catalog endpoint documenting all query parameters
• Include stability level in search results and capability references
• Add glossary (GLOSSARY.md) and API contract (docs/catalog-api-contract.md)
• Add ADR 0001: drop deprecated=since:<version> filter in favor of simple yes/no

Changed

• BREAKING: Change /api/search type values from PascalCase to lowercase (Resource → resource, Attribute → attribute, Operation → operation, Capability → capability)
• Update default MGT test image to WildFly 42
• Bump quarkus-neo4j from 6.8.0 to 6.8.1

Fixed

• Enforce cross-type AND semantics in catalog (e.g., type=operation&dataType=string correctly returns zero results)
• Strip invalid type parameter values instead of returning 500 errors
• Cap catalog page size at 500 to prevent unbounded result sets
