Summary

This PR adds or corrects source metadata (source {} blocks in METADATA.pb) for 74 font families, along with upstream_info.md investigation reports for each. One additional commit (Ewert) updates an upstream_info.md whose METADATA.pb change was already merged to main independently.

Each commit touches exactly one family and contains METADATA.pb + upstream_info.md + config.yaml (where applicable).

Override config.yaml files included

For 9 families where the upstream repo has gftools-builder-compatible sources but no config.yaml, an override is provided directly in the google/fonts family directory. The config_yaml field is intentionally omitted from METADATA.pb in these cases — google-fonts-sources auto-detects the local override.
