// Package chat provides chat channel management for the EverQuest II server emulator.
//
// The chat system provides comprehensive channel-based communication with membership,
// access control, and message routing capabilities. It supports both persistent world
// channels (loaded from database) and temporary custom channels (created by players).
//
// Basic Usage:
//
//	db, _ := database.NewSQLite("chat.db")
//
//	// Create new channel
//	channel := chat.New(db)
//	channel.ID = 1001
//	channel.Name = "Auction"
//	channel.ChannelType = chat.ChannelTypeWorld
//	channel.Save()
//
//	// Load existing channel
//	loaded, _ := chat.Load(db, 1001)
//	loaded.Delete()
//
//	// Load by name
//	auction, _ := chat.LoadByName(db, "Auction")
//
// Master List:
//
//	masterList := chat.NewMasterList()
//	masterList.LoadAllChannels(db)
//	masterList.AddChannel(channel)
//
//	// Find channels
//	found := masterList.GetChannel(1001)
//	byName := masterList.GetChannelByName("Auction")
//	worldChannels := masterList.GetWorldChannels()
//	activeChannels := masterList.GetActiveChannels()
//
// Channel Management:
//
//	// Channel membership
//	err := channel.JoinChannel(characterID)
//	inChannel := channel.IsInChannel(characterID)
//	members := channel.GetMembers()
//	err = channel.LeaveChannel(characterID)
//
//	// Access control
//	channel.SetLevelRestriction(10)
//	channel.SetRacesAllowed(raceFlags)
//	channel.SetPassword("secret")
//	canJoin := channel.CanJoinChannelByLevel(playerLevel)
//
// Channel Types:
//
//	// World channels - persistent, loaded from database
//	channel.ChannelType = chat.ChannelTypeWorld
//
//	// Custom channels - temporary, created by players
//	channel.ChannelType = chat.ChannelTypeCustom
//
// The package includes comprehensive access control with level, race, and class
// restrictions using bitmask filtering, optional password protection, and
// integration interfaces for client communication, player management, and
// multilingual chat processing.
