Soften workspaces page-title (#774)

"From review surfaces to integrated verification systems" reads like a
slide title. Replacing with "From review surfaces to standards your
agents learn from" which still captures both ideas (verification +
agents that improve from the team's reviews) but drops the corporate
phrasing.
