Build macOS notification bridge for the target arch

Browse Source 
The macOS notification bridge is compiled by build.rs outside Cargo's Rust target handling. On Apple Silicon, clang defaulted macos_notifications.o to arm64 even when Cargo was building x86_64, so the x64 release job ignored the object and missed the exported notification symbols.

Constraint: The ObjC bridge is linked manually through cargo:rustc-link-arg
Constraint: Release workflow builds both aarch64-apple-darwin and x86_64-apple-darwin from macOS runners
Rejected: Rely on clang default architecture | Apple Silicon defaults arm64 and breaks x86_64 linking
Confidence: high
Scope-risk: narrow
Directive: Keep native ObjC bridge compilation aligned with Cargo TARGET when adding platform bridge files
Tested: cargo fmt --check
Tested: git diff --check
Tested: cargo check --target aarch64-apple-darwin
Tested: cargo build --target x86_64-apple-darwin --release
Tested: file target/x86_64-apple-darwin/release/.../macos_notifications.o reports Mach-O 64-bit object x86_64
Not-tested: Full GitHub release workflow after retag before pushing
