- Move geometry package from _demo to cl/_testdata/geometry1370
- Create simplified test in cl/_testgo/interface1370 following interface test pattern
- Generate .ll file with llgen to verify interface metadata package path fix
- Remove old demo files (issue1370_geometry, issue1370_goast, issue1370_gotypes)
- Remove .tmp-comment files
The new test structure is simpler and follows the existing cl/_testgo/interface pattern,
focusing on demonstrating the interface metadata fix for private methods across packages.
