VolmLib pin removal

- The build resolves VolmLib master-SNAPSHOT when no sibling checkout is substituted
- The native runtime manifest, roots and keep rules come from the embedded natives
- The packed jar natives are verified against the embedded provider shas
- Every jar carries META-INF/volmit/volmlib.properties
- The build logs the resolved VolmLib once
- publishedNativeRuntime, the loader coordinate flags, mavenLocal and publish-volmlib are gone
