[Bug] PATH validation fails when $HOME contains special characters (@)

Bug Description
Claude constantly reports: Native installation exists but ~/.local/bin is not in your PATH. Run:
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc && source ~/.zshrc even when the path is correct and set in .zshrc and there is only one installation of claude code present. My $HOME has an '@' in it. This may be causing it a problem?
