Fixed: Finder windows no longer get stuck half-tiled.

• With two overlapping Finder windows, the tiling completion check could borrow an already-tiled sibling window's geometry, wrongly declare the window done and never retry. CG window evidence is now bound to the exact window (identity gate + size-delta gate for occluded windows that macOS drops from the CG list).
• Windows whose size writes are silently rejected by the app (macOS 26, e.g. some Finder states) now degrade to centered instead of being pinned half-tiled to the tile origin; later tile attempts short-circuit instead of replaying the move-fail-recenter loop.
• Off-screen / overhanging windows are pulled back to center, and same-app windows across multiple displays are each laid out with their own screen's context (coordinate-space ties now resolve to the canonical global top-left semantics).
• Same-pattern CGWindowList misuse fixed in the UI snapshot and self-test tooling.

462 tests pass. Plan and evidence: docs/fix-plan-finder-tile-misjudgment.md.

修复：Finder 窗口不再卡在半平铺状态。

• 两个 Finder 窗口重叠时，平铺完成判定可能借用已平铺兄弟窗口的几何，误判完成且永不重试。CG 窗口证据现在绑定到确切窗口（身份门 + 被遮挡窗口剔除列表的尺寸差分门）。
• 被应用静默拒绝尺寸写入的窗口（macOS 26 的部分 Finder 状态）改为降级居中，而不是缺一块钉在平铺原点；后续平铺尝试直接短路，不再重演「滑过去—失败—拉回来」。
• 屏幕外/悬空窗口会被拉回居中；同一应用跨多屏的多窗口各自使用所在屏幕的上下文正确布局（坐标空间平票时回归全局 top-left 规范语义）。
• UI 截图与自测工具中的同款 CGWindowList 误用一并修复。
