freehire-search: lean search uses the web endpoint; drop unread params (#631)

semantic_ratio and include_description are both reported in
meta.ignored_params. With include_description ignored, the agent endpoint
hydrates every full body from the database, and --no-description threw
that payload away client-side. Send --no-description to /api/v1/jobs/search,
which serves only the preview, and stop sending the two unread params.
