[BUG] Installation instructions for fish shell are incorrect

What's Wrong?

When you install Claude Code using the recommended installer in the documentation, you get this message after the installation is wrapping up:

⚠ Setup notes:
  • Native installation exists but ~/.local/bin is not in your PATH. Run:

  echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.config/fish/config.fish &&
  source ~/.config/fish/config.fish

This is just straight-up incorrect, and will not do what is intended. Fish is a very popular shell, so it should provide appropriate instructions for that shell.

What Should Happen?

It should give proper instructions for adding ~/.local/bin to your PATH. My suggestion would be to use fish_add_path.

Steps to Reproduce

Just run the installer script in a fish shell. As of writing, that command is:

curl -fsSL https://claude.ai/install.sh | bash

Is this a regression?
