Add CLAUDE.md for Claude Code guidance

[iliyan-velichkov]

Summary

Adds a CLAUDE.md to give Claude Code instances quick orientation in this repository.

Key points captured:

• This repo is a thin Spring Boot distribution assembling Eclipse Dirigible components — most behavior lives in upstream org.eclipse.dirigible:* artifacts and the platform parent POM, not here.
• Helios is the API-focused JavaScript edition of the codbex platform (https://www.codbex.com/products/): a lean pro-code environment for building Enterprise APIs, deliberately omitting heavier engines like BPM and CMS. Scope is expressed entirely via application/pom.xml.
• Build/run commands (incl. required --add-opens flags) and Maven profiles (quick-build, unit-tests, integration-tests, tests, format).
• Test layout: trivial contextLoads unit test vs. Selenium-based integration tests, plus single-test invocation.
• Module architecture: application defines the product via its dependency list; branding/components are packaged as Dirigible registry content; menu-help/welcome override upstream equivalents.
• Configuration via dirigible.properties and Spring profile activation.
