fix(macos): show capsule in fullscreen Spaces

[H-Chris233]

User description

Summary

• Add NSWindowCollectionBehavior::FullScreenAuxiliary to the macOS capsule no-activate show path.
• Keep CanJoinAllSpaces and orderFrontRegardless so the capsule remains visible without focusing OpenLess.
• Extend the macOS capsule Spaces contract test to cover fullscreen auxiliary behavior.

Fixes #548

Test Plan

• npm --prefix "openless-all/app" run check:macos-capsule-spaces
• cargo test --manifest-path "openless-all/app/src-tauri/Cargo.toml" capsule_show_strategy_matches_platform_activation_contract -- --test-threads=1
• npm --prefix "openless-all/app" run build
• git diff --check

Notes

• cargo check --manifest-path "openless-all/app/src-tauri/Cargo.toml" --target x86_64-apple-darwin cannot complete on this Linux machine because the macOS SDK is unavailable (TargetConditionals.h missing from the ring build). Real macOS fullscreen smoke testing is still required.

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ✅ 548 - PR Code Verified Compliant requirements: The no-activate path still uses set_visible_on_all_workspaces(true) and orderFrontRegardless. The capsule window now opts into NSWindowCollectionBehaviorFullScreenAuxiliary. A contract test was added for the capsule Spaces behavior. Requires further human verification: Verify on a real macOS system that the capsule is visible after switching to another desktop and in fullscreen Spaces.
