fix: clean Go module paths before calling OSV API

- OSV API expects clean module paths like 'gorm.io/driver/sqlite'
- Cache keys include Go proxy format like 'gorm.io/driver/sqlite/@v/v1.6.0.zip'
- Added cleanGoModuleName() to extract module path and version
- Strips /@v/ prefix and .zip/.mod/.info suffixes
- Fixes 404 errors when scanning Go modules

Resolves: OSV API returning 404 for Go module scans
