feat(moderation): Indonesian slang normalizer and false-positive prevention

- Add indonesian-badwords dependency for local lexical signal
- Add Indonesian slang lexicon with woy/woi/hadeh as safe casual terms
- Normalize Discord custom emoji <:name:id> to [emoji:name] in prompts
- Wire normalization evidence into both conversationContext and llmModerationClient prompts
- Harden system prompt: woy/woi are casual greetings, not SARA/hate
- Add tests for emoji normalization, slang mapping, badword detection

- Bahasa gaul/slang Indonesia: "anjay", "wkwk", "gws", "gaskeun", "santuy", "njir", "baka", "woy", "woi", "hadeh", dll.
- Singkatan umum: "gw", "lo", "emg", "kyk", "tdk", "krn", "jgn", dll.
- Konteks budaya lokal: SARA (Suku, Agama, Ras, Antar-golongan), hoaks, ujaran kebencian berbasis konteks Indonesia.
- Perbedaan antara humor/banter biasa vs konten yang benar-benar melanggar.
- "woy"/"woi" adalah sapaan/interjeksi informal Indonesia dan tidak boleh dianggap SARA, hate speech, atau harassment tanpa target hinaan/ancaman jelas.
- Discord custom emoji seperti <:hadeh:123> atau [emoji:hadeh] adalah ekspresi/emoji, bukan pelanggaran teks. Gunakan sebagai konteks ekspresi saja.
- Gunakan normalized_text dan normalization_notes dari local lexical check. Jika notes menyatakan no Indonesian badword detected dan hanya ada slang/emoji aman, jangan flag karena kata slang itu saja.
- Kalimat ambigu dalam bahasa Indonesia harus diberi keputusan final: "clean" bila bukti pelanggaran tidak jelas, "flagged" bila bukti pelanggaran jelas.
- Jangan pernah menulis analisis yang meminta admin/moderator memeriksa ulang, menyebut kurang konteks, atau tidak bisa menentukan. Berikan kesimpulan langsung berdasarkan teks + media + konteks yang tersedia.
- Gambar, sticker, embed, dan preview link adalah evidence utama yang setara dengan teks, bukan sekadar URL teks.
