Introduces four independent flags to skip individual packaging artifacts:
-Dpkg.skip.bootjar=true skip spring-boot repackage (*-boot.jar)
-Dpkg.skip.deb=true skip Gradle buildDeb + Maven attach-artifact
-Dpkg.skip.rpm=true skip Gradle buildRpm
-Dpkg.skip.zip=true skip maven-assembly-plugin Windows ZIP
Adds -Dpkg.skip=true as a single convenience flag that sets all four
at once. msa/pom.xml mirrors the skip-pkg profile to override its own
<pkg.deb.phase>package</pkg.deb.phase> property (child POM properties
have higher priority than parent profile properties in Maven).
msa/* docker modules used ${basedir}/../.. (non-canonical) for main.dir.
maven-enforcer-plugin 3.5.0's osIndependentNameMatch() compares
file.toURI() vs file.getCanonicalFile().toURI() — these differ when the
path contains '..', causing RequireFilesExist to report false-negative.
Fix: replace ${basedir}/../.. with ${maven.multiModuleProjectDirectory}.
