Summary

• Use plain-text release category headings.
• Strip emoji characters from the complete generated release body, including PR titles and direct commit subjects.
• Ask contributors to keep PR titles emoji-free and document the release behavior.

Validation

• swift build
• swift test --filter DocsContractTests
• bash -n scripts/generate_macos_release_notes.sh
• Parse .github/release.yml
• Generate notes against the current release history and assert the result contains no emoji characters.
• git diff --check

The existing v0.48.2 draft description was updated with the same emoji-free generator output. Its assets and tested source commit are unchanged.
