We have a lot of verbose headers, and i think now is the best opportunity we have to become reuse compliant given that we just did two other similar maintenance changes (prettier, typescirpt5 & eslint9 & typescript-eslint). * synapse_antispam resuse headers. * delete old unused tslint.json. * Add REUSE to pre-commit config. * reuse info for config directory.
