What happened?

1. Bump @biomejs/biome from 2.4.6 to 2.4.7
2. Biome format removes curly bracket in speculation rules
3. Parser fails with "Expected a semicolon or an implicit semicolon after a statement, but found none"

Expected result

Parser should not fail and format shouldn't been changed to invalid
