Fix duplicate Swift bridge symbols in release builds

[SpectralDragon]

Summary

• give all header-only Swift bridge helpers internal linkage with static inline
• prevent the helpers from being emitted as duplicate external symbols by multiple Swift translation units
• preserve the existing Swift/Clang bridge API and behavior

Validation

• reproduced the original ld: 5 duplicate symbols failure with a focused production build before the fix
• swift build -c release passes after the fix
• swift test -c release passes all 4 Gravity VM tests
• AdaEditor universal Release build passes for arm64 and x86_64 with the updated dependency revision
