merge: merge atsunatsu/main (mutual radar overlay arrows)

Merge upstream commit 2298d8ee 'feat: add mutual radar overlay arrows'. Clean auto-merge: upstream changed RadarView.kt arrow drawing, our sweep optimization stayed intact. No conflicts.

First v4.4.5 was built from c3444aed; this release rebuilds from the merged tree.
