Fixes #43

Changes

loadChatHistory(agentId) / saveChatHistory(agentId, messages) helpers in ui.js using localStorage key matrix:chat:<agentId>
Cap at 100 messages per agent (oldest dropped first on overflow)
Each message stored with a timestamp field, displayed as [HH:MM] prefix
appendChatMessage persists to localStorage on every call (user send + assistant response)
renderChatHistory(agentId) restores history on page load / panel open
clearChatHistory(agentId) + CLEAR HISTORY button in Chat tab header wipes stored history and re-renders empty
WebSocket and session message paths wired through appendChatMessage for full persistence
No backend changes
