[Feature Request] Improve session switching and active session visibility in VSCode extension

Bug Description
Seria interesante tener una mejor vista sobre las sesiones que se encuentran en curso y poder pasar entre ellas con mas facilidad, desde la extensin de vscode eso no es algo sencillo, porque entonces hay que darle clic a cada una para recordar que estaban haciendo, porque nisiquiera hay un simbolo que te deje saber que esta trabajando. Es mas facil abrir varias terminales de claude code, pero para quienes estamos usando la extension de Claude Code en VSCode, la idea es tener una mejor experiencia. Me parece que n ese sentido Copilot tiene una mejor UI/UX.
