refactor: merge /me + /channels into /state, unify message endpoints

Browse Source 
- HandleState returns user info (id, nick) + joined channels in one response
- HandleGetMessages now serves unified message stream (was HandlePoll)
- HandleSendMessage accepts 'to' field for routing to #channel or nick
- HandleGetHistory supports scrollback for channels and DMs
- Remove separate HandleMe, HandleListChannels, HandleSendDM, HandleGetDMs, HandlePoll
