v0.0.31: per-bot unique user IDs, remove raw fingerprint from bot API

Privacy: from.id is now Hash(bot_token + user_fp) → different bots see
different numeric IDs for the same user. Prevents cross-bot user correlation.

Removed id_str (raw hex fingerprint) from all bot API responses.
Updated LLM_BOT_DEV.md and LLM_HELP.md.
