fix(release): conventionalcommits preset so semantic-release keeps ! commits

Switch commit-analyzer and release-notes-generator from the angular default
to the conventionalcommits preset so feat!:/fix!: breaking commits are no
longer silently dropped. Add the conventional-changelog-conventionalcommits
devDep and a workflow guard step that fails if a release-worthy feat/fix
commit produces no release.
