fix: Configure ESLint to use ignores pattern instead of .eslintignore

- Added ignores pattern to eslint.config.js for flat config
- Excludes node_modules, .obsidian, build outputs, etc.
- Removed deprecated .eslintignore file
- Follows gitignore patterns for consistency
- Fixed formatting issues in config file
