Restructure project to use Maven exclusively and bump to v1.0.1-SNAPSHOT

- Remove legacy Ant build system (build.xml, sources/ directory)
- Migrate to Maven-only build with standard directory structure
- Add comprehensive Maven documentation and JAVA_HOME setup for Fedora
- Update pom.xml with exec plugin and bump version to 1.0.1-SNAPSHOT
- Add CLAUDE.md for development guidance
- Update README.md with detailed build/run/clean instructions
