test: demote setup-gbrain Path 4 E2E to periodic-tier

Browse Source 
The Agent SDK E2E tests for Path 4 (skill-e2e-setup-gbrain-remote and
skill-e2e-setup-gbrain-bad-token) are inherently non-deterministic —
the model interprets "follow Path 4 only" prompts flexibly and can
skip Step 8 (CLAUDE.md write) or shortcut past the verify helper, which
makes the gate-tier assertions flaky.

The deterministic gate coverage for Path 4 is in
test/setup-gbrain-path4-structure.test.ts: a fast structural lint that
catches AUQ-pacing regressions and prose contract drift in <200ms with
zero token spend. That test is the right tool for catching the failure
mode the gate-tier was meant to guard against.

The Agent SDK E2E tests stay available on-demand for periodic-tier runs
(EVALS=1 EVALS_TIER=periodic bun test test/skill-e2e-setup-gbrain-*.test.ts).
Also tightened the verify-error assertion to the literal field shape
("error_class": "AUTH") instead of a substring match that false-matches
the parent claude session's "needs-auth" MCP discovery markers.
