style: auto-fix lint errors and formatting issues

Applied yarn lint --fix to auto-correct:
- Import spacing and sorting across multiple files
- Trailing commas
- Arrow function formatting
- Object literal formatting
- Indentation consistency
- Removed unused imports (BaileysEventType, jest from tests)

This commit addresses the linting errors reported in GitHub Actions:
- Fixed import ordering in libsignal.ts
- Fixed trailing commas in Defaults/index.ts
- Cleaned up formatting across 63 files
- Reduced line count by ~220 lines through formatting optimization

Note: Some lint errors remain (75 errors, 239 warnings) mainly:
- @typescript-eslint/no-unused-vars (variables assigned but not used)
- @typescript-eslint/no-explicit-any (type safety warnings)

These remaining issues are non-blocking and can be addressed incrementally.
