refactor: Rename generatorUrl to _generatorUrl and add schema enhancements

Schema Changes:
- generatorUrl → _generatorUrl (consistent with underscore prefix pattern)
- Added _installUrl for full .json URLs (pattern: ^https?://.*\\.json$)
- sourceUrl_ → _sourceUrl (moved underscore to prefix)
- iconUrl_ → _iconUrl (moved underscore to prefix)
- Added deprecation notes for old properties

Site.js Changes:
- Updated to check data._generatorUrl instead of data.generatorUrl
- Added support for data._installUrl with full URL validation
- Maintains backward compatibility

Sources.json Changes:
- S.to-like Generator: generatorUrl → _generatorUrl
- Follows standard underscore prefix convention for extensions
