Search the Charity Commission register of England and Wales by name or keyword.
Returns matching charities with registration number, status, and
registration date. Use charity_profile for full details once you
have the charity number. The upstream `searchCharityName` endpoint
returns the full list in one shot — pagination is applied
client-side via offset/limit. A query that matches nothing is a
successful empty result (`charities: []`), not an error — the
upstream endpoint signals "no matches" with an HTTP 404, which is
translated back into an empty result here rather than surfaced as
a not-found failure.
