Use askQuestions tool in memory slash command when invoked from chat context

[Copilot]

The /memory slash command used QuickPick UI unconditionally. When invoked from a chat context, it should use the askQuestions tool instead for inline UX. The presence of toolInvocationToken distinguishes chat invocation from Command Palette invocation.

Changes

• Thread toolInvocationToken through slash command layer: Added optional param to IClaudeSlashCommandHandler.handle() and IClaudeSlashCommandService.tryHandleCommand(), passed from request.toolInvocationToken at the call site in claudeChatSessionContentProvider.ts
• MemorySlashCommand: branch on token presence: When toolInvocationToken is present, invoke CoreAskQuestions via IToolsService.invokeTool() with memory locations as question options. Falls back to existing QuickPick path when absent (Command Palette).

async handle(
    _args: string,
    stream: vscode.ChatResponseStream | undefined,
    _token: CancellationToken,
    toolInvocationToken?: vscode.ChatParticipantToolToken
): Promise<vscode.ChatResult> {
    if (toolInvocationToken) {
        return this._handleWithAskQuestions(stream, toolInvocationToken);
    }
    // existing QuickPick path
}

Tests

New memoryCommand.spec.ts covering: tool invocation with token, skipped answers, empty responses, tool errors.

Original prompt

In the memory slash command for the Claude agent integration, I want the slash command invocation to use the askQuestions tool instead of the quick picks.

I think you'll need to pass down the chatinvocationtoken and use the presence of that as a signal to use either the quick picks or the tool.
