Tyler Slaton 3d4912f323 fix(showcase/langgraph-python): close remaining D5 cells (framework + fixtures)
Lands the Bucket A framework fix and the fixture-correctness changes
needed to flip the remaining D4/D2 cells in the langgraph-python column
to D5. Full local D5 sweep is green (1 passed, 0 failed).

Framework: every Python `ToolMessage` constructed via `Command(update=...)`
now sets `name=` and `id=str(uuid.uuid4())`. Without these, @ag-ui/langgraph
synthesises TOOL_CALL_START events with `toolCallName: null` and
`parentMessageId: null`, which @ag-ui/client@0.0.53's Zod schema rejects;
the rejection is silently swallowed by `withAbortErrorHandling -> EMPTY`,
completing the SSE observable mid-stream so post-tool state never reaches
the consumer. Fix is applied across shared_state_streaming, shared_state_read_write,
gen_ui_agent, beautiful_chat, subagents (2 sites). Single-flag change in
a2ui_dynamic flips the secondary `_design_a2ui_surface` LLM call to
`streaming=True` so aimock's record/replay (SSE-only) sees it.

Fixtures (d5-all.json):
- toolCallId follow-ups for set_steps (3), display_flight, generate_a2ui (4),
  schedule_meeting (2), generateSandboxedUi (7), and revenue chart so
  multi-turn probes don't recurse into recursion-limit loops
- four hand-crafted secondary `_design_a2ui_surface` fixtures so A2UI
  dynamic renders without a real LLM
- mcp-apps fixture rewritten to emit `create_view` tool call with a
  minimal Excalidraw element payload; runtime middleware fetches the UI
  resource and the iframe mounts
- AAPL and revenue `hasToolResult: true` follow-ups tightened to
  `toolCallId` so they don't match cross-turn after prior turns' tool
  results
- voice fast-path content-only fixture
- beautiful-chat-schedule-meeting first-turn fixture gains content so
  the conversation runner sees an assistant message before the picker
  click assertion

Probes: bumped per-card waitForSelector in d5-gen-ui-headless-complete from
15s to 60s — recharts ResponsiveContainer can be slow under 4 sequential
turns.

Shell-dojo: hide CLI Start Command from the dojo navigation via
`HIDDEN_DOJO_FEATURE_IDS`. Registry/manifests untouched so
harness/parity/dashboard still see it.
