Window behaviour fixes for the custom title bar.
Edge resizing, Aero Snap and double-click-to-maximize now work. A borderless window loses the styles Windows needs to act on its own hit-test results, and docked child controls were covering the resize edges; both are corrected, and all four interactions were measured rather than assumed.
Includes everything from v0.1.2: transparent application icon, the white-cell fix on bound rows, the warning before overwriting an externally changed config, translations moved to locale/*.json, and the package version now taken from Directory.Build.props.
