[Feature Request] Add commands.local or gitignore-compatible private commands

Environment

• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [x] Other: Max Plan
• Claude CLI version: 1.0.58 (Claude Code)
• Operating System: Windows 11, WSL2, Ubuntu 24.04.2 LTS

Bug Description

I believe Project commands are version-controlled and shared with the team through git, while personal commands exist at the environment root level and aren't tracked. However, there's a middle ground I'm trying to achieve - commands that I want available for a specific project but don't want to share publicly with the team.

I attempted to solve this by placing commands in .claude/commands/somedir within the project and adding somedir to .gitignore, but this approach prevents Claude from detecting them entirely. It would be valuable to have either a commands.local feature or the ability to gitignore command directories while still making them accessible to Claude.

The key issue is needing project-specific commands that remain private to individual developers rather than being shared across the entire team.

Steps to Reproduce

1. Create a nested commands directory
2. Add it to .gitignore
3. Typing /

Wanted Behavior

Having the commands available.

Actual Behavior

Claude does not list the ignored commands
