chore: Update .gitignore

This commit updates the `.gitignore` file to include build directories for several project modules, ensuring that compiled artifacts and build-specific files are not tracked by version control.

- Added `/core/build/`
- Added `/core-build/build/`
- Added `/feature-location/build/`
- Added `/feature-settings/build/`
- Added `/feature-weather/build/`
