Media lows: safe mime suffix, exact game forms, ext map, WAV check, album skip log, mg cap (A6-5..A6-11, A1-5)

Comment cleanup: short Russian why-comments, no AI boilerplate

Luna audit round 2: review fixes (regex bounds, mixed albums, redaction guards)

Luna audit fixes: album lock, multilingual routing, streaming budget, quota and persistence hardening

Comment polish: Russian pro-style comments, keep dated evidence short (+426/-2765). Fix: bot.send_chat_action -> bot.bot.send_chat_action (was AttributeError, typing indicator never showed)

Finish audit leftovers: speed_key dedup, truncate in formatting, honest mime suffixes, filename sanitize, tiger boundary, dead image data, deterministic timing tests, HEALTHCHECK, dependabot (AUD-B-003, AUD-E-005, AUD-E-006, AUD-K-001, AUD-M-001, AUD-M-004)

Per-chat bot language (/lang, 6 languages) plus single EN system prompt
