Feature Request

The session dropdown in the webchat interface currently shows the full session keys like:

• agent:main:subagent:caf556fc-0598-4109-b066-3563f8a3fd8a

These are not human-friendly. When sessions have labels (like valet-pm, fsi-pm), show those instead.

Current: agent:main:subagent:674dbb74-6ebb...
Expected: valet-pm or valet-pm (agent:main:subagent:674...)

The sessions_list API already returns labels. This is a frontend display change.
