fix(macos): native window chrome — system rounded corners, shadow, traffic lights - #400

…d corners The main window was created frameless (decorations: false), which on macOS produces a square, shadowless NSWindow. A macOS platform config now decorates the window with an overlay titlebar (hidden title, traffic lights at 14,13): the system draws rounded corners, shadow, and traffic lights, while the app titlebar keeps its custom content and drag handling. The custom window controls and edge resize handles no longer render on macOS - the decorated window provides both natively. Windows 11 already rounds resizable frameless windows via DWM; Linux compositors have no equivalent standard, so both stay frameless.
…config Review follow-ups: WindowControls drops its unreachable macOS ordering branch (the component never renders on macOS now); the Settings window-controls row hides on macOS where it governed nothing; README documents the per-platform chrome; a unit test pins tauri.macos.conf.json to the base window entry so a base-config edit cannot silently skip macOS (the platform merge replaces the windows array wholesale).

Closes #399
What changed
src-tauri/tauri.macos.conf.json: macOS platform overlay — the main window is decorated with an overlay titlebar (titleBarStyle: Overlay, hidden title, traffic lights at 14,13), so the system draws rounded corners, shadow, and traffic lights. Windows/Linux keep the existing frameless chrome (Windows 11 already rounds resizable frameless windows via DWM).WindowControlsandResizeHandlesrender nothing on macOS — the decorated window provides controls and resize natively. The unreachable macOS ordering branch inWindowControlsis removed.tauri.conf.jsonentry (the platform merge replaces thewindowsarray wholesale — RFC 7396), plus an AGENTS.md note, README chrome docs, and an UNRELEASED.md entry.Tested

Review
Local review: standard risk class, one independent reviewer (Opus 5, correctness/regressions + KISS + issue conformance). No P0–P2; five P3s, all fixed in
9ab65b5^..(README docs, dead branch, inert Settings row, drift-guard test, live nav-click verification). KISS verdict after fixes: keep.
