feat(ci): publish desktop release bundles

[owjs3901]

Summary

• let changepacks create the draft release, then build Windows, macOS, and Linux bundles
• isolate build jobs from release write credentials and pin every reusable action
• normalize five native artifacts and publish the release only after every platform succeeds
• use the changepacks package version plus native Windows/macOS installer icons and Korean MSI metadata

Verification

• bun run lint
• bun run test (79 Bun tests, 180 Rust unit tests, 34 Rust integration tests)
• bun run build
• actionlint 1.7.12 .github/workflows/ci.yml
• local Windows NSIS and MSI builds plus artifact normalization
• independent code review: no blocking findings
