Bug: `.codegraph/.gitignore` fails to prevent the `.codegraph/` directory itself from being tracked by Git

[SunYanbox]

The current .codegraph/.gitignore file generated by codegraph by default looks like this:

# CodeGraph data files
# These are local to each machine and should not be committed

# Database
*.db
*.db-wal
*.db-shm

# Cache
cache/

# Logs
*.log

# Hook markers
.dirty

This configuration causes an issue: when running git status in the project root, you'll notice that the .codegraph/ directory is still being tracked by Git. The reason is that although there is a .gitignore file inside this directory, the file itself is not ignored, so the entire .codegraph/ directory remains under Git's version control.

I understand that the intent of .codegraph/.gitignore is to ignore specific file types inside the directory, but the current approach doesn't fully achieve the effect of "ignoring the entire .codegraph/ directory."

Suggestion: Would it be possible to either add .codegraph/ to the root .gitignore file, or use * inside the generated .codegraph/.gitignore to ignore all contents while explicitly excluding the .gitignore file itself? For example:

# Automatically generated by codegraph
*
!.gitignore

This would ensure that the entire .codegraph/ directory is not tracked by Git while preserving the .gitignore file itself.

Thank you for your consideration!
