[aidenybai]

Add an ambient event context system with a floating copy badge to silently track user interactions and provide a contextual trail for coding agents.

Summary by cubic

Adds ambient hover/click tracking with a toolbar trail copy button that shows a count and copy feedback. Auto-copies the trail on window blur; removed the floating badge UI.

• New Features

  • Track hover/click when not selecting: 400ms hover dwell, 100ms de-dupe, hover→click subsumption, max 10 entries, 60s freshness.
  • Trail store with copy formatting; toolbar button shows count and a check on copy (1.5s). Renderer wired via eventContextTrailCount, eventContextCopyStatus, onCopyEventContext; export EventContextEntry.

• Refactors

  • Removed the ambient copy badge and related signals; simplified core tracking to just the trail with copy in the toolbar.
