Summary by cubic

Adds LeTrain to the Game Development → Frameworks list to broaden coverage of active Java game projects. This highlights an open-source procedural train simulator built with Java 17, LibGDX, and Lanterna.

• Single-line addition in README_SOURCE.md under the Frameworks subsection.
• Uses the canonical GitHub link and a concise description; no other edits.
• No build or runtime impact; README.md will reflect this after the next generation step.

^{Written for commit 2604024. Summary will update on new commits.}
