fix(dom/events): ensure mouseReleased fires after DOM interactions

[sidhansu10]

Summary

Fixes an issue where interacting with p5 DOM elements (e.g. createSelect)
in Safari triggers mousePressed but not mouseReleased, leaving
mouseIsPressed stuck in a true state.

Details

• Safari does not always propagate mouseup back to the canvas after DOM interactions
• This patch forwards DOM mouseup events to p5’s internal mouse handler
• Guarded to only trigger when mouseIsPressed is true
• Implemented centrally in addElement to cover all p5 DOM elements

Resolves #8293
