test(e2e): privacy-gate AskUserQuestion fires from preamble (periodic tier)

Two periodic-tier E2E tests exercising the preamble's privacy gate
end-to-end via the Agent SDK + canUseTool. Previously uncovered:

- Positive: stages a fake gbrain on PATH + gbrain_sync_mode_prompted=false
  in config, runs a real skill, intercepts tool-use. Asserts the
  preamble fires a 3-option AskUserQuestion matching the canonical
  prose ("publish session memory" / "artifact" / "decline") and does
  NOT fire a second time in the same run (idempotency within session).

- Negative: same staging but prompted=true. Asserts the gate stays
  silent even with gbrain detected on the host.

Registered in test/helpers/touchfiles.ts as `brain-privacy-gate`
(periodic) with dependency tracking on generate-brain-sync-block.ts,
the three gstack-brain-* bins, gstack-config, and the Agent SDK runner.
Diff-based selection re-runs the E2E when any of those change.

Cost: ~$0.30-$0.50 per run. Only fires under EVALS=1 EVALS_TIER=periodic;
gate tier stays free.
