Add healthcare/ division: Clinical Evidence Agent and Sovereign Health Systems Agent (#655)

Agents developed by Snark Health (github.com/snark-health).

Snark Health was founded by a practicing US physician with 25 years
of internal medicine and infectious disease experience and direct
leadership of a $2 billion risk-based Medicare bundled payment
contract with the US government, and a Kenyan engineer and operator
whose collaboration with the founding physician began in 1998 in
rural western Kenya. The frameworks in these files come from a team
that has delivered care in both US hospital systems and
resource-limited settings, managed actuarial risk under government
contract, and built health infrastructure across two continents
over 25 years.
