feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish

Extension changes:
- sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab()
  swaps entire chat view, browserTabActivated handler for instant tab sync,
  stop button wired to /sidebar-agent/stop, pollTabs renders tab bar
- sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup,
  input placeholder "Ask about this page..."
- sidepanel.css: tab bar styles, stop button styles, loading state fixes
- background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel
  with tab URL for instant tab switch detection
