The headers for source and trigger registration are now unified under `Attribution-Reporting-Register-Source` and `Attribution-Reporting-Register-Trigger`, respectively, and the `aggregation_keys` are now stored as a JSON dictionary. Debug keys must be set in the source and trigger headers, and script tags can now register attribution sources. Additional updates include removing `window.registerSource` and adjusting report generation.\n"]]
