[BUG] Changes to `.claude/` are not detected until session restart

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

When I make changes to .claude/, they are not detected until session restart. Examples of this include:

• Adding a new skill or slash command file
• Editing an existing skill or slash command file

What Should Happen?

When I make changes to .claude/, Claude Code should either:

• Watch that directory and update the references it has to those files
• Show an alert (in the CLI and the SDK) indicating that the .claude/ directory is out of sync with the Claude Code process.

Error Messages/Logs

Steps to Reproduce

1. Run claude
2. Add a new slash command (at a location like .claude/commands/test-skill.md)
3. Send a message asking to use that new slash command, and Claude will respond that it does not have that slash command.
