Summary

• On macOS, multi-clicks were sent as repeated single clicks, which some UI targets treat as separate clicks.
• This change sets kCGMouseEventClickState per down/up event so the OS recognizes double/triple clicks.
• click(clicks=N) on macOS now routes through a single _multiClick call to preserve click state sequencing.

Behavior change

• macOS multi-click now uses the correct click state on each event.
• This aligns doubleClick()/tripleClick() behavior with native expectations (e.g., desktop icon activation, multi-click selection in editors).

Regression notes

• Potential risk: Some apps that previously responded to repeated single clicks might now treat them as a true multi-click (double/triple) and behave differently.
• We still emit the same number of down/up events; only the click state metadata changes.

Test plan

• Double-click a desktop icon: should open as expected.
• Double-click in a text editor: should select word.
• Triple-click in a text editor: should select paragraph.
