[Bug] respectGitignore: false does not allow @mentioning gitignored files

Bug Description
The respectGitignore: false doesn't seem to fully allow me to @ mention files that are .gitIgnored, which can be very annoying for planning markdowns and stuff that i have purposefully gitignored but want to be able to reference in a Claude Code session
