[BUG] `/memory` command creates a new CLAUDE.md file *and* also writes to `.gitignore` to ignore that file *without permission*

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [X] Other: <!-- specify --> Claude Code from VS-Code, also reproduced in Terminal (zsh).
• Claude CLI version: <!-- output of claude --version --> 0.2.55
• Operating System: <!-- e.g. macOS 14.3, Windows 11, Ubuntu 22.04 --> 15.3.2
• Terminal: <!-- e.g. iTerm2, Terminal App --> VS-Code Terminal, also reproduced in zsh.

Bug Description

<!-- A clear and concise description of the bug -->

I invoked the /memory slash-command, which opens a menu to select which CLAUDE file you want to edit (project, project local, or user/system). I selected an option which didn't exist yet, so Claude created it. It also wrote to my .gitignore to ignore the file. I guess the instructions kind of tell you that it's going to create a git-ignored file, but I did not expect this behavior. I think it would be clearer if you stated that the .gitignore file will be automatically updated/written-to without approval - this was totally confusing to me.

I just created a blank directory and started Claude. I immediately ran /memory and these are the options:

Project memory                 Checked in at ./CLAUDE.md                        │
│    Project memory (local)         Gitignored in ./CLAUDE.local.md                  │
│    User memory                    Saved in ~/.claude/CLAUDE.md  

The directory is not even a git repo (not git-initialized yet). So these options are definitely confusing/wrong.
