This pull request introduces several enhancements to the model classes for architecture and code models, primarily to support improved persistence and reconstruction from storage (e.g., Neo4j). The main changes include adding constructors that accept explicit IDs for restoring objects, integrating persistence logic in ModelStates, and minor API.

Pull request overview

This PR adds a Neo4j-backed persistence layer for ARDoCo models, documentation graphs, trace links, and inconsistencies, and wires it into selected TLR/ID pipelines through a shared persistence bridge.

Changes:

Adds a new core/neo4j-schema module with Neo4j entities, repositories, mappers, services, Spring Boot activation, and tests.
Extends core model APIs with reconstruction constructors and adds PersistenceBridge/PersistenceHandler integration in shared state/helper classes.
Adds integration tests and pipeline setup changes for Neo4j-backed persistence across documentation, architecture, code, trace link, and inconsistency flows.

This Testcontainers dependency is used only by tests but is added without test scope, so consumers of the neo4j-schema module inherit Testcontainers artifacts on their main classpath. Mark it as test scope like the org.testcontainers:neo4j dependency above.

Deleting one preprocessed text removes all sentence-based trace links and all text inconsistencies before deleting the requested document. In a database containing multiple persisted texts, removing one identifier will wipe links/inconsistencies for the others as well. Scope the cleanup to sentences belonging to the given identifier instead of deleting by relationship type globally.
