/context command output not visible in VSCode extension

Description

When running the /context command in the VSCode extension, the output is not displayed to the user, even though the command executes successfully and the output is included in the conversation context.

Steps to Reproduce

1. Open Claude Code in VSCode extension
2. Run /context command
3. Observe that no output is displayed

Expected Behavior

The context usage breakdown (tokens, MCP tools, memory files, skills, etc.) should be visible in the chat interface.

Actual Behavior

No output is displayed to the user. However, the output IS being generated - it appears in the conversation context and is visible to Claude, just not rendered for the user.

Environment

• Platform: macOS (Darwin 25.2.0)
• Interface: VSCode extension
• Model: claude-opus-4-5-20251101

Additional Context

The output that should be visible includes:

• Token usage breakdown by category
• MCP tools table
• Custom agents table
• Memory files table
• Skills table

This suggests a rendering/display bug rather than a command execution issue.
