Add clarification about when to run install commands

[daveey]

TL;DR

Added clarification about when to run installation commands in CLAUDE.md

What changed?

Added a note in CLAUDE.md explaining that users typically don't need to run install.sh or metta install commands unless they're experiencing import or setup issues.

How to test?

1. View the updated CLAUDE.md file
2. Verify the new clarification appears between the initial command examples and the "Commands" section

Why make this change?

To prevent unnecessary reinstallation by clarifying when installation commands should actually be used, helping users avoid running these commands when they don't need to.
