DeepSeekEyes 0.5.0

• Add window-scoped native observation on Windows and macOS, with screenshot-relative coordinate mapping back to the desktop and explicit failure instead of silently returning the wrong scope.
• Add Windows UI Automation and macOS Accessibility element discovery with stable elementRef identities, semantic role/name/value/bounds/state metadata and configurable observation limits.
• Re-resolve macOS Accessibility actions by a stable semantic fingerprint and duplicate ordinal, using the prior flat index only after identity/bounds verification so a shifted tree fails closed instead of acting on another control.
• Prefer semantic elementRef actions while retaining pixel-coordinate fallback: click/type/scroll now accept elements, and new invoke, set_value and perform_action operations call native accessibility patterns.
• Derive stable windowRef values from native window identity while keeping all refs bound to the latest stateId.
• Bind macOS windows to stable CoreGraphics window numbers and re-resolve the matching Accessibility window after z-order changes, preventing a focus/raise action from capturing another window of the same application.
• Return stateDelta after every observation, including pixel-identity screenshot changes and added/removed/changed windows and elements.
• Add native runtime assertions for window existence/title, element existence/visibility/enabled/focus/value/name and screen changed/unchanged, while retaining explicit model-backed visual assertions.
• Upgrade desktop reports to deepseekeyes.desktop-report.v2; typed text, assigned values and launch arguments remain plaintext-free in persisted events.
• Add GUI settings for semantic desktop observation and element limits, increase the default desktop timeout to 30 seconds, and document the 0.5 screenshot/action/feedback loop.
• Extend unit and native acceptance coverage for window capture, semantic refs/actions, state differences, runtime assertions and macOS Accessibility; Windows helper parsing/native observation remain covered by cross-platform CI.
• Keep Windows desktop discovery valid when no window-scoped semantic target exists by normalizing the UI Automation result to an explicit empty array before counting controls.
