1.2.0 Improved entity and keyword parsing

• Added a dedicated entity parser that normalizes strings, strips possessive suffixes, and deduplicates people, places, organizations, and topics before returning them
• Introduced reusable helpers for capitalizing text, removing trailing possessives, and stripping punctuation
• Updated the keyword parser to apply these helpers so extracted keywords and keyphrases are capitalized and free of trailing possessives
• Loaded NLP plugin hints into the main parse workflow to enrich entity detection
• Expanded test coverage to verify entity capitalization, possessive stripping, and keyword/phrase normalization
• Removed domain specific tweaks from scripts as they are no longer required
