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.
