Summary

• follow up the existing macOS Spaces/fullscreen capsule fixes by keeping the capsule window in its overlay configuration after startup and after hide
• replace macOS window.hide() on the capsule path with an AppKit orderOut helper so the window does not get rebound to a regular Space
• harden the static macOS capsule contract test around the new overlay behavior

Why the current implementation still breaks

Previous fixes in #549 and #556 taught the capsule how to join all Spaces and fullscreen Spaces at show time. That helps for the first show, but the Tauri window still goes through the regular hide() path:

• startup hides the capsule with window.hide()
• idle/hidden transitions also call window.hide()

On macOS, that means the next show is starting from a normal hidden NSWindow state again, so the overlay can still fall back to the app's own desktop Space instead of the current fullscreen Space.

This patch keeps the existing webview capsule, but treats its NSWindow more like a non-activating HUD overlay:

• clear MoveToActiveSpace and Stationary
• keep CanJoinAllSpaces + FullScreenAuxiliary
• add Transient, IgnoresCycle, and the non-activating panel style bit
• hide with orderOut instead of the regular Tauri hide() path

Verification

• npm --prefix "openless-all/app" run check:macos-capsule-spaces
• git diff --check

Notes

• I could not run cargo test in this fork clone because the checkout is missing the vendor/qwen-asr C sources required by build.rs.
• The behavior itself was smoke-tested separately on a local macOS build while narrowing this patch down from a larger self-use branch.

PR Type

Bug fix, Tests

Description

• Overlay capsule on fullscreen macOS Spaces

• Configure NSWindow with proper collection behavior, style mask, and window level

• Hide capsule with orderOut instead of window.hide() to keep space association

• Add unit tests and update contract test for new helpers
