/agents: take the remote-session sentence off the page

FRE-323 removed the remote claim from the landing page and missed the second
page that carries it. /agents said 'Agents can run on this Mac or on remote
machines over SSH — remote sessions report into the same grid', which is the
same unverified claim (FRE-315 §1, FRE-320), in front of the same launch
traffic. Removed; the paragraph now ends at 'the agent keeps its own prompting'.

Not deployed: same read-only credential as c1c498e.
