chore: bump to v1.27.3 — CI fixes, ring linker fix, draft releases

- fix: CI Windows NSIS upload — let tauri-action handle artifact upload directly
- fix: Linux/AUR ring linker error — cc + -fuse-ld=bfd via .cargo/config.toml
- fix: releases now created as draft for review before publishing
- chore: consolidate 1.27.0–1.27.2 changelog into single entry
