Pull request overview

This PR modernizes the linting and formatting infrastructure by adopting a shared ESLint configuration (@feedic/eslint-config) and introducing Biome for code formatting. The changes upgrade ESLint from version 9 to version 10 and replace Prettier with Biome.

Changes:

• Upgraded ESLint to v10.0.1 and integrated @feedic/eslint-config shared configuration
• Added Biome (v2.4.4) for formatting and removed Prettier dependency
• Applied automated code formatting across all source files (import ordering, arrow function conversions, etc.)
