v6.4.0

Added

• bots chat type — New bots option for CHAT_TYPES to back up bot conversations. Previously, bot chats were silently skipped because they didn't match any chat type (private, groups, channels). Add bots to your CHAT_TYPES to include them. Bots share PRIVATE_INCLUDE/EXCLUDE_CHAT_IDS lists for per-type filtering. Backward compatible — existing configs without bots are unaffected.
