v1.2.0

Changed

• Menu bar app event buffer raised from 100 to 500 events in memory.
• Scroll list shows last 50 events (was 30).
• Header counter now tracks total events since last Clear, not just the buffer size.
  The counter keeps climbing even after the 500-event buffer trims older entries.

Added

• "Showing last 500" indicator appears when the event buffer is full.
• README and project docs updated for v1.1.2 dedup fixes, sync behavior, and test suite.
