/help lists /tdd ~20 times despite only 2 source files on disk

Description

/help lists the /tdd slash command approximately 20 times with identical descriptions, despite only 2 source files existing on disk: ~/.claude/commands/tdd.md and ~/.claude/skills/tdd/SKILL.md. All duplicate entries show (user) tag, indicating they are being registered from user space.

The duplication appears to be a registration/rendering bug in Claude Code — there are no additional copies of the file on the filesystem.

Steps to reproduce:

1. Have a tdd.md in ~/.claude/commands/ and a tdd/SKILL.md in ~/.claude/skills/
2. Open the slash command menu (type /)
3. Observe /tdd listed ~20 times with description "Remind agent about TDD approach and continue conversation (user)"

Expected: /tdd listed once (or at most twice if both the command and skill register separately).
Actual: /tdd listed approximately 20 times.
