- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome. - Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'. - Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock. - Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters. - Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.
