…raph 0.0.41 bump)

@ag-ui/client 0.0.56 changed runHttpRequest to a thunk signature, breaking
@copilotkit/core's ProxiedCopilotRuntimeAgent. OSS-248 only needs
@ag-ui/langgraph 0.0.41; keep that, revert the unrelated core/client/protocol
'latest' bump. Adopting client 0.0.56 is a separate migration.

## What

Adopts the new `ag-ui-langgraph` single-arg tool-factory API in
CopilotKit's LangGraph middlewares, and upgrades the `@ag-ui/*`
dependencies to the latest published releases.

Counterpart to ag-ui-protocol/ag-ui#1894 (OSS-248: re-enable A2UI
generation & design guidelines via the shared `A2UIToolParams` bag).

## Commits

1. **`feat(a2ui): use new ag-ui single-arg A2UIToolParams API`**
- sdk-python + sdk-js middleware: `get_a2ui_tools`/`getA2UITools` now
take a single `A2UIToolParams` object (model inside);
`composition_guide` folds into the `guidelines` bag.
- Guarded `A2UIToolParams` import (py); typed import (ts). a2ui test
skip-reason wording.
- Pins: `@ag-ui/langgraph 0.0.40` (js, the release carrying the new
API), `ag-ui-langgraph >=0.0.41` (py).

2. **`chore(deps): use latest @Ag-ui packages and langgraph
integration`**
- `@ag-ui/core`, `@ag-ui/client`: `0.0.53 → 0.0.56` across all packages
+ root pnpm override.
- `@ag-ui/langgraph` (runtime): `0.0.39 → 0.0.40`. `ag-ui-protocol
>=0.1.19`.
- `.npmrc`: exclude first-party `@ag-ui/{core,client,encoder,proto}`
from the minimum-release-age gate so the freshly-published `0.0.56` set
installs.
   - Regenerated `pnpm-lock.yaml` + `sdk-python/poetry.lock`.

3. **`chore(showcase): align a2ui to single-arg get_a2ui_tools API`**
   - `showcase/.../graph.ts`: `getA2UITools(model, opts)` → single-arg.

## Notes

- All `@ag-ui` deps are live on npm/PyPI, so the branch installs
cleanly.
- Showcase **docs** alignment (TS backend tabs for dynamic-schema) is
still being sorted out — the per-integration docs architecture needs
untangling first; deferred to a follow-up.
