feat(ontologies): add Ontologies service for UiPath knowledge graph management

Implements the full OntologyService covering CRUD on ontologies and
component file operations (upsert, bulk-upsert, get, list, delete,
validate). Wires up the `@uipath/uipath-typescript/ontologies` subpath
export with ESM/CJS/UMD dist output. Integration tests are skipped
pending API deployment (target mid-July 2026).
