fix: restore case-insensitive java globbing for licenses, version and nested jars

The `archiveEntries` refactor dropped `GlobMatch`'s case-insensitive flag, so with nested cataloging
off (the default) three lookups that main matched regardless of case became case-sensitive:

- license files under `/META-INF/*` and `/*` (`meta-inf/LICENSE` was missed)
- `/version.properties`
- the `**/*.jar`, `**/*.war` check behind the "nested archives not cataloged" unknown, so `LIB.JAR`
  slipped past it

`archiveEntries` now has a `globFold` for those call sites. The zip side restores
`GlobMatch(true, ...)`, and the resolver side matches case-folded over every entry, since resolver
globs are case-sensitive.
