GLSP-1636: Compile before linting to resolve workspace imports

The example app now consumes @eclipse-glsp/ide via 'workspace:*', so
import-x/no-unresolved fails unless the package's lib output exists.
Run 'compile' from the 'lint' script (and 'build' in 'check:all') so
linting works on a clean tree, including the CI Lint job.
