WinHub 1.1.2

A performance and efficiency pass over the always-on hot paths — WinHub runs 24/7, so idle cost matters.

Fixed

• System monitor no longer leaks Mach ports. Each CPU/memory sample leaked two host-port references (~86k/day at the default interval). The port is now acquired once and reused.
• Dock previews can no longer close the wrong window. When a window's title changed between capture and click, the thumbnail's ⊗ used to fall back to the app's first window — now a failed match does nothing instead of closing an arbitrary window. (Click-to-raise keeps the benign fallback.)
• Stale album art on track changes. Skipping to a track that carries no artwork used to keep the previous track's cover and accent color in the notch; it now clears.

Changed

• Lighter media watching. Album artwork is only decoded when it actually changes — previously the full cover was base64-decoded on the main thread on every progress update (several times a second while playing). Artwork is also downsampled once (max 512 px) off the main thread, so the ambient glow's blur no longer processes full-resolution art every frame.
• Cheaper Dock hovering. A cursor resting over the Dock no longer re-runs the Accessibility hit-test and app resolution 16×/second — it only re-checks when the cursor moves. The Dock's position is cached instead of read from preferences on every poll tick.
• Leaner window thumbnails. Previews capture at the size they're actually displayed (scaled for Retina) instead of up to 4–5× larger, and the system window list is briefly cached when sweeping across several Dock icons.

Install: download the DMG, drag WinHub to Applications. First launch: right-click → Open (release is un-notarized).
