fix(react-ag-ui): preserve user message attachments when converting to AG-UI format

• toAgUiMessages() previously called extractText() for user messages, silently dropping image and file attachments
• User messages with attachments now emit AG-UI InputContent[]: images map to the image variant with a data or url source, files map to the binary variant preserving filename
• Falls back to plain string content when no binary parts are present, preserving backward compatibility

fix(react-google-adk): render user-authored events as human messages

AdkEventAccumulator.processEvent previously routed author: "user" events through getOrCreateAiMessage, producing type: "ai" messages that convertAdkMessage mapped to role: "assistant" — so user text rendered as assistant bubbles. With Workflow agents this caused full multi-turn conversations to merge into a single assistant block. User events now create type: "human" messages, preserving text, inline images, and file references.

fix(react-google-adk): allow HITL interrupt tool UIs to render with requires-action status

• makeAssistantToolUI for HITL tools (adk_request_input, etc.) can now use status.type === "requires-action" to render input forms
• Non-HITL final events still receive their manual complete status

fix(react-google-adk): don't auto-cancel HITL interrupts when user sends a new message

• useAdkRuntime.onNew now filters pending tool calls whose id is tracked in long_running_tool_ids, so ADK HITL interrupts (adk_request_input, adk_request_confirmation, adk_request_credential) are no longer overwritten with {cancelled: true} when the user types a new message
• Add useAdkSubmitInput(toolCallId, result) to submit the user's answer as a {result} FunctionResponse, matching ADK's unwrap_response contract so Workflow RequestInput nodes resume with the unwrapped value
• AdkEventAccumulator unions long_running_tool_ids across events instead of replacing, so multiple HITL interrupts in the same turn are all tracked
• onEdit / onReload / session load paths now reset derived HITL state (longRunningToolIds, toolConfirmations, authRequests, escalated) via a new replaceMessages helper on useAdkMessages, so stale interrupt markers don't leak into the next turn

Behavior change: HITL interrupts must now be answered through a tool UI using the dedicated submit helpers (useAdkSubmitInput, useAdkConfirmTool, useAdkSubmitAuth). Typing in the composer while an interrupt is pending no longer sends a spurious cancellation.

feat(react-langgraph): support LangSmith Generative UI ui_message

• Translate UI messages into DataMessageParts on the associated assistant message, rendered via the existing makeAssistantDataUI({ name, render }) API
• Accumulate UI messages from both custom stream events (raw {type:"ui"} / {type:"remove-ui"}) and the values.ui state snapshot
• Key UI entries by ui.id, shallow-merge props when metadata.merge === true, delete on type:"remove-ui"
• Expose uiStateKey config option for graphs that customize the typedUi state key
• Extend the load callback return type with uiMessages so persisted UI state can be restored on thread switch
• Expose useLangGraphUIMessages() for accessing the raw UI message list
• Export UIMessage, RemoveUIMessage, and UseLangGraphRuntimeOptions types

Behavior change: {type:"ui"} / {type:"remove-ui"} payloads received on the custom stream channel are now intercepted by the adapter before reaching eventHandlers.onCustomEvent. Other custom events still reach the handler unchanged.
