fix: improve detector accuracy based on QA findings

- profanity: add leet substitutions 9→g and 8→b to catch newer evasion variants
- responsible: add 10 injection patterns for roleplay, hypothetical framing,
and indirect requests (both Indonesian and English)
- ner: exclude known idioms (Ibu Kota, Ibu Pertiwi, Bapak Bangsa) from
person entity rule via negative lookahead; fix PT/CV rule to only consume
capitalized words, preventing greedy match into surrounding sentence
- pii: tighten address pattern so Desa/Kelurahan/Kecamatan only trigger when
followed by additional address components (RT/RW/Kab/Kec), reducing
false positives in narrative text
