Bug Description

Installation for Kiro-cli fails for non-Admin users on MacOS (see below, cs is a standard user account, so is an admin user account).
After installing as admin user, kiro-cli is not installed into PATH.

$ curl -fsSL https://cli.kiro.dev/install | bash                                                                                ─╯

Steps to Reproduce

1. install kiro-cli into a non-admin account on MacOS
2. install fails badly
3. install using an admin account
4. Kiro-cli is not added to PATH

Expected Behavior

• detect if current user as admin rights, if not, ask for them
• alternatively, look for an already existing installation in standard locations, then augment the path accordingly when installing as non-admin user
