Add CLAUDE.md with build commands and architecture guidance

[iliyan-velichkov]

Summary

• Adds CLAUDE.md to guide Claude Code (and human onboarding) in this repo.

What it documents

• What this repo is: Iapetus is a codbex product — "Integrations Management for ETL and other enterprise integration patterns based on Apache Camel" (Integrations Modeler and Flows). Technically a thin assembly/packaging layer over Eclipse Dirigible: most behavior comes from dirigible-components-* deps, and application/pom.xml is effectively the product definition.
• Module layout: roles of application/, components/ (Dirigible content, not Java), branding/, and integration-tests/ (selects upstream Dirigible suites).
• Build/test/format commands: the platform parent's Maven profiles (quick-build, unit-tests, integration-tests, tests, format), required --add-opens JVM flags, and a single-IT-class invocation.
• Runtime config: the Spring-profile model (common,app-default, provider profiles) and the org.eclipse.dirigible scan with excluded JDBC/JPA autoconfig.
• Conventions: EPL-2.0 headers; where to add bundled capabilities vs. custom UI content.
