Feat property specific label maps

[rmfranken]

Proposed Changes

label map is now predicate specific - meaning you can't match "Python" the snake for ex:programmingLanguage.

Pull Request Overview

This PR implements predicate-specific label maps to prevent mismatches like matching "Python" the snake for a programming language predicate. The key change is transitioning from a single global label map to predicate-specific label maps based on SHACL PropertyShape constraints.

Key changes:

• Refactored label map structure from flat dictionary to predicate-specific nested dictionaries
• Updated RDFTransformer to use the new predicate-specific approach
• Removed global ambiguity handling in favor of immediate failure on predicate-level duplicates
