CSV Anonymizer v1.0.21

• Add optional Local AI smart replacement for selected columns through Ollama and Gemma 3 4B, including status checks, model download controls, and validated replacement maps with rule-based fallbacks.
• Rename the end-user deterministic setting to Repeatable replacements and clarify that the seed is private and useful for matching replacements across files.
• Extend privacy reporting with smart replacement columns, generated smart values, and fallback counts while preserving the existing local-first anonymization warnings.
• Keep model weights and local runtime binaries out of source and release metadata, with checks that block tracked .gguf, model-cache, Ollama-cache, and llama-server artifacts.
