fix(agent): drop the empty assistant turn from an approved-action replay

The approved-action replay appends the sealed tool result with no assistant
prose for that round, which produced an assistant message with content "".
Anthropic's Messages API rejects a non-final assistant message with empty
content, so a resumed turn after a tool approval failed before the model saw
the result. A turn carrying neither prose nor reasoning has nothing to say to
any provider, so it is no longer appended. A round with prose, and a
reasoning-only round that DeepSeek thinking mode needs, both still append.

+"""Pin the shared config cache in static/js/appConfig.js.
+
+Background: /api/auth/settings was fetched independently by six modules and
+/api/tools by three (chatRenderer.js is imported under three different ?v=
+query strings, so it is three separate module instances) — 4 and 3 requests on
+one cold load. Beyond the redundant work, each caller could observe a different
+snapshot of the same object. appConfig.js gives them one promise each.
+
+The two properties that matter are opposites, so both are tested here:
+concurrent and later callers must NOT refetch, and a caller after a write MUST
+see the new value — which only holds if every writer invalidates. The last test
+is a source scan that checks exactly that, since a forgotten invalidation
+serves a stale settings object for the rest of the session, which is worse than
+the duplicate fetches this replaces.
+
+Driven through `node --input-type=module` so the real module runs, same idiom as
+test_esc_menu_stack_js.py. The module source is inlined rather than imported by
+path because the repo has no `"type": "module"` in package.json; appConfig.js
+has no imports of its own, so inlining is exact. `fetch` and `sessionStorage`
+are stubbed, so nothing here touches the network or depends on timing.

+fail loudly on a name nobody registered (rather than handing back `undefined`
+and blowing up somewhere unrelated), and it must not memoise a *failed* load —
+otherwise a panel that failed to load once while offline would stay broken for
+the rest of the session.
