feat: add source bundle via maven-assembly-plugin

Produces code-iq-VERSION-source-bundle.zip/.tar.gz during mvn package.
Contains the full project source tree (src/, pom.xml, README, LICENSE,
.github/, ANTLR grammars) without build artifacts (node_modules, dist,
generated sources, target/).

Bundle is ~1.3MB compressed. Attached as a Maven artifact for
distribution alongside the compiled JAR.
