refactor: strip AI slop from README

[ShovalBenjer]

3 specific changes:

1. Removed "state-of-the-art", "novel", "unparalleled accuracy", "highly capable yet lightweight", "incredibly fast", "blazing-fast", "next-generation" and all other hollow adjectives throughout
2. Replaced the three-column feature/impact table and verbose roadmap section with tight prose; all real numbers (97.8%, 8789 ingredients, 0.6s, 135x, ~1.4s) kept in place
3. Cut the multi-paragraph stage deep-dives and McKinsey-style Problem/Solution/Architecture/Components structure down to a flat 4-item numbered list and a performance table
