Remove ambiguous tools: Get-Metadata, Camera Trace, DetURL (THE-137)

These three entries do not map to identifiable standalone public OSINT tools.
Research across multiple sources could not confirm their existence as distinct,
maintained tools. They can be re-added if concrete replacements are identified.
