[BUG] Plugin skill "rc:status" intercepts built-in /status command via fuzzy match

What's Wrong?

Typing /status in the prompt resolves to the RevenueCat plugin skill rc:status instead of the built-in /status command. Built-in commands should not be overridable by plugin skills via substring matching.

What Should Happen?

Built-in commands (/status, /usage, etc.) should always take priority over plugin skills, regardless of fuzzy matching.

Steps to Reproduce

1. Install the RevenueCat plugin (rc@claude-plugins-official)
2. Type /status in the prompt
3. RevenueCat's rc:status skill is invoked instead of the built-in status command
