test(gbrain): relax E2E assertions to smoke-test contract

Browse Source 
Per codex #12 (AgentSDK harness is non-deterministic): the E2E now
asserts the model followed the split-engine path WITHOUT requiring a
specific subcommand sequence. Three assertions:

  1. AskUserQuestion was called (model reached interactive branches)
  2. At least one of {gstack-gbrain-install, `gbrain init --pglite`,
     `claude mcp add`} fired (model followed the skill, not a no-op)
  3. The fake bearer token never leaked to CLAUDE.md (security regression)

Deterministic per-step coverage of the same flow lives in the gate-tier
unit tests (gbrain-local-status, gbrain-sync-skip, init-rollback,
upgrade-migration). The E2E exists to catch the "model can't follow
the skill at all" regression class, not to pin the exact tool sequence.

Test passes in 280s against the live Agent SDK.
