Overview page doesn't mention PATH setup after native install

### Documentation Type

Missing documentation (feature not documented)

### Documentation Location

https://code.claude.com/docs/en/overview

### Section/Topic

Terminal install – "Get started" section, native install next steps

### Current Documentation

The docs say to run:

cd your-project
claude

right after the native install command. That's the only "next step" shown.

### What's Wrong or Missing?

When ~/.local/bin isn't already on PATH, the install.sh script itself prints a warning with the fix:

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

But the Overview page's "Get started" section doesn't mention this at all, so users who don't read the terminal output carefully just get "claude: command not found" with no explanation on the page itself. Suggest adding a short note/troubleshooting link right under the `claude` command on this page, e.g. linking to /docs/en/troubleshoot-install or stating the PATH fix directly.

### Suggested Improvement

Add a short note or troubleshooting link directly under the `claude` command in the "Get started > Terminal" tab, e.g.:

If `claude` isn't found after installing, `~/.local/bin` may not be on your PATH yet. Run:

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

See troubleshoot-install for more.

(Adjust for zsh/other shells as appropriate.) This mirrors the warning the install.sh script itself already prints, so it should just need surfacing on this page too.

### Impact

High - Prevents users from using a feature

### Additional Context

_No response_

Open the Overview page at https://code.claude.com/docs/en/overview and inspect the Get started > Terminal tab alongside the PATH warning printed by install.sh. Add a concise note or troubleshooting link beneath the claude command, then verify that the page explains what to do when ~/.local/bin is not on PATH and points to troubleshoot-install.
