refactor(ethos): rename Boil the Lake principle to Boil the Ocean

Reframes the completeness principle so the ocean (the complete thing) is the
goal and lakes are the boilable units you ship on the way there. "Don't boil
the ocean" was right when engineering time was the bottleneck; AI killed that
bottleneck, so the ocean is now the destination.

Resolves an existing split: the scope_appetite psychographic, archetypes, and
the completeness intro flow already used "boil the ocean" as the
complete-implementation pole while the named principle still said "lake".

resolvers, and the plan/autoplan/document-generate templates.
