xarmian 7b46894413 fix(e2e): silence cross-actor SSE creation toasts suite-wide (BUG-2334)
The e2e suite shares one pad instance and one workspace, so items seeded
by OTHER concurrently-running specs arrive over SSE and stack
"X created: ..." info toasts bottom-right — directly over bottom-right UI
(the graph drawer's detail card), turning unrelated specs' clicks into a
race. pane-content-link-anchors:238 paid a ~40-minute rerun tail at
nearly every merge gate.

The fix is a narrowly-scoped test-surface kill switch, not a retry:

- `quietExternalToasts()` (toast store): reads a localStorage flag no
  production code ever sets; never throws whatever storage does.
- The ONE call site announcing another actor's SSE work — the external
  `item_created` toast in the workspace layout — checks it. Toasts the
  page earns with its own actions are untouched, so specs still exercise
  the real toast surface (copy-dialog's no-force-click policy keeps its
  protective value).
- The shared e2e fixture installs the flag on every context via
  `quietCrossActorToasts()`; collab-persistence's self-built contexts
  install it explicitly; account-delete's contexts never enter workspace
  routes and stay bare.
- sse-toast-quiet.spec.ts pins BOTH sides: the quiet leg anchors on the
  layout branch's own by-uuid GET (pre-attached response log — no
  arm-order race; SSE-stream response gates the create; bounded settle
  before the negative assert), and a deliberately unflagged CONTROL
  context proves the product toast still fires — the real behavior
  cannot silently regress behind the suite-wide silence.

Evidence: three consecutive full local suite runs with ZERO failures
(baseline: 1-3 interception/load flakes per run); unit tests pin the
helper's contract. Reviewed to fresh-angle CLEAN over four Codex rounds
(vacuous-anchor, arm-order, SSE-connectedness, and self-built-context
holes all found and fixed by the loop).
