Bug: /context command incorrectly resolves to /compact even when typing full command

Description

When typing /cont, the CLI defaults to /compact instead of /context. This prefix-matching behavior is understandable. However, even when typing the full /context command, it still resolves to /compact.

Steps to Reproduce

1. Open Claude Code CLI
2. Type /context (the full command)
3. Press Enter

Expected Behavior

Typing /context (the full command name) should execute the context command.

Actual Behavior

/context resolves to /compact instead.

Environment

• Claude Code CLI
• Windows (also likely affects other platforms)

Additional Context

The command prefix resolution appears to prioritize /compact over /context alphabetically or by registration order, but typing the complete command name should bypass prefix matching and execute the exact match.
