[BUG] Agents are installed in wrong folder if not in project root when running /agents

Environment

• Platform (select one):
• [ x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.84
• Operating System: macOS
• Terminal: Terminal App

Bug Description

If the /agents command is used to install a new agent, and you currently are in a subfolder (due to previous claude code work), the agent will be installed in a new .claude/commands folder in the subfolder. The install wizard will be completed, but the agent will never run unless moved into the correct folder.

Steps to Reproduce

1. Start claude
2. Do some work that put you in a subfolder (which is not always clear unless statusbar is installed)
3. Install an agent for Project (not User)

Expected Behavior

Agent should be installed in correct project root folder

Actual Behavior

Installed in wrong location
