fix(ai-moderation): audit prompts to reduce false positives

- ENTROPY rule: replace 'PILIH WARN' default with 'PILIH CLEAN'
- Add safe-list for code/log/stack traces/project names
- Narrow sexual_deviation: only flag explicit sexual solicitation
- Remove overbroad ontological graph (kostum hewan → furry) detection
- Add clean few-shot examples: error logs, project names, orientation disclosure
- Update simple fallback prompt with FP prevention rules
- Remove LGBT/furry from offensive username criteria
