v0.9.3

Bug Fixes

• Auth storage: Bot and user identity are now stored separately in keyring and auth.yml. Previously, StoreUserInfo was called for both token types, so whichever was stored last would overwrite the other — causing self-DM detection and ResolveUserID() to return the wrong identity.
• Self-DM detection: Now uses client.AuthUserID() (live auth.test call) instead of reading stored user info, making it reliable regardless of storage state.
• ResolveUserID: Only uses the user token now (not bot token), since bot token returns the bot's identity, not the human's.

Internal

• New keyring keys: bot_user_id, bot_user_name for bot identity
• New auth.yml fields: bot_user_id, bot_user_name
• StoreBotUserInfo() / GetBotUserInfo() functions
• Login and app create flows now store bot vs user info to the correct keys
• Tests for separate bot/user info storage
