v0.6.4

# GPUI Kit v0.6.4

GPUI Kit v0.6.4 is a patch release on top of v0.6.2. It fixes popup placement on tiled Linux windows, where a menu opened near the window edge no longer lined up with its trigger, and closes two pie chart rendering issues.

## Components

- **Popup**: on a client-decorated window the edge clamp now honors the window's tiling. A tiled edge draws no shadow, so a `Popover`, `PopupMenu`, `DropdownMenu`, `Select`, or tooltip opened near the left or right edge of a tiled window (every window on Hyprland and other tiling compositors) keeps only the popup's own margin and stays aligned with its trigger instead of being pushed 20px inward; an untiled edge still keeps the client inset. ([#3130](https://github.com/longbridge/gpui-kit/pull/3130))
- **Chart**: a `PieChart` without an explicit `outer_radius` paints and hit-tests with its laid-out radius again instead of rendering nothing, and a hovered slice's leader line starts at the lifted slice edge so it no longer cuts into the fill. The gallery's "Revenue by Region" labels fit their card. ([#3123](https://github.com/longbridge/gpui-kit/pull/3123), [#3121](https://github.com/longbridge/gpui-kit/pull/3121))

Thank you to everyone who contributed code, documentation, testing, and feedback!
