Support hiding attached session

[joshmedeski]

As a user, I want to optionally flag if the attached session should be shown.

• The tmux processSessions function needs to always return the attached session to prevent Connecting twice to existing and opened session gives error #46
• I don't think this should be a global config (just a CLI flag)
• Make it something like --hide-attached for now (not sure if there's an alias that would be clear)
• Hide the zoxide result that matches the attached session? (will cause a bug if someone chooses it)

I can pick this up.

It appears that this flag (and --json but i dont really care) is unimplemented in sesh v2.

#currently in a session named 6
sesh list --hide-attached | head -n 1
# 6
sesh --version
# sesh version 2.0.2

I think I've found where it is printing, and I don't think it's filtering for --hide-attached

sesh/seshcli/list.go

Lines 62 to 68 in 9380ad3

	for _, i := range sessions.OrderedIndex {
	name := sessions.Directory[i].Name
	if cCtx.Bool("icons") {
	name = icon.AddIcon(sessions.Directory[i])
	}
	fmt.Println(name)
	}

Even though connecting to the opened session no longer gives an error. I still think there is a benefit of removing some of the clutter during the selection of sessions.

Something went wrong with the implementation, I need to revisit this.
