chore: release metadata -- author of record, URLs, schema ceiling, 0.3.0

Authors@R was an org with no human, so citation() and the r-universe
maintainer page had nothing to render and ORCID could not collate this
with merTools. The given-name vector c("Jared", "E.") matches merTools
exactly; person("Jared", "E. Knowles") would render the same but put the
middle initial in the family-name slot.

MaxCorpusSchema claimed 5 while .validate_schema() accepts 4-7 and the
published corpus is 7 -- metadata contradicting code by two versions.

0.3.0 rather than 0.2.0: remote reads go from broken to working and the
default URL from placeholder to live, which is user-visible behaviour.
