feat: add release changelog generation and package distribution integration

feat: add custom release changelog generator based on release tag ranges and prefixed commit lines
build: include generated CHANGELOG.md in the distribution ZIP when present
ci: generate release changelog during release workflow and use it as the GitHub release body
ci: split release packaging so distZip is rebuilt after changelog generation
chore: keep changelog generation out of quality-gate and report publishing workflows
