Make the Eve onboarding checkpoint run against the contract that exists

The portability workflow has been red since 2026-08-22. Three things,
each hidden behind the one before it:

- Eve started refusing to build a command intent for a surface that has
  not advertised a command boundary and receipt schema (Eve 4338a42,
  2026-08-22). The two-runtime sample never advertised one. It now passes
  a provider advertisement with worldInteraction for its surface, which is
  the declaration the lowering was right to demand.
- The sample and the package-closure script still imported "cultcache-ts";
  the package became @gamecult/cultcache-ts on 2026-09-04 (8cb3b72) and
  CI never got far enough to say so. Two READMEs carried the same import.
- The job pinned Eve to codex/eve-browser-host-isolation, a branch that was
  never merged and stopped moving on 2026-08-25. The sample is written
  against Eve main and passes there; the pin now says so.

The interop workflow's Python step ran one test file by path; it now
discovers the three split suites.
