Root cause

The SPA sends pointer coordinates normalized to 0..65535 relative to the captured frame. MacInput posted those values directly as CoreGraphics global points. On Retina displays and offset secondary monitors, clicks therefore landed far from the visible cursor.

Fix

map normalized coordinates into the active CoreGraphics display rectangle
apply logical-point scaling for Retina displays and virtual-desktop offsets
seed the mapping in helper-managed and fallback in-process paths
cover move, click, and wheel positioning

Verification

RED/GREEN unit tests for Retina center and offset secondary-display edges
cargo test -p zeno-agent (185 unit + 12 integration/source guards passed)
cargo clippy -p zeno-agent --all-targets -- -D warnings
cargo fmt --all --check
git diff --check
