fix(faith): locate romcal root by walking up from main entry

romcal's package.json is not listed in its exports map, so
require.resolve('romcal/package.json') throws ERR_PACKAGE_PATH_NOT_EXPORTED
under Node's strict exports enforcement. Resolve the main entry instead
and walk up until we find the package.json belonging to romcal itself.
