fix: improve Codecov coverage reporting configuration

Changes:
1. CI workflows now generate coverage with --coverage flag
2. Added explicit coverage file path (./coverage/lcov.info)
3. Added coverage metadata (flags, name) for better tracking
4. Enhanced Jest config with coverage configuration:
   - Collect coverage from src/**/*.js
   - Exclude test files and node_modules
   - Generate lcov and html reports
   - Set 70% coverage thresholds

This resolves the 'No coverage reports found' error in CI
