[hydraxman]

Describe the bug

When using AzureCliCredential in a non-interactive environment (e.g. IntelliJ IDEA plugin, background service, or other GUI-based Java applications on macOS), authentication fails with:

To Reproduce

1. Install Azure CLI on macOS using Homebrew
   (e.g. /usr/local/bin/az or /opt/homebrew/bin/az)
2. Use AzureCliCredential in a Java application running in a non-interactive / GUI environment
   (e.g. IntelliJ IDEA plugin)
3. Ensure /bin/sh is invoked without a login shell or user PATH initialization
4. Call AzureCliCredential.getToken(...)

Code Snippet
Add the code snippet that causes the issue.

Expected behavior

• correctly locate the Azure CLI executable when it is installed, or
• provide a clearer error indicating PATH resolution issues

Screenshots
If applicable, add screenshots to help explain your problem.

Setup (please complete the following information):

• OS: MacOS
• IDE: IntelliJ
• Library/Libraries: [e.g. com.azure:azure-core:1.16.0 (groupId:artifactId:version)]

• App Server/Environment: [e.g. Tomcat, WildFly, Azure Function, Apache Spark, Databricks, IDE plugin or anything special]
• Frameworks: [e.g. Spring Boot, Micronaut, Quarkus, etc]

If you suspect a dependency version mismatch (e.g. you see NoClassDefFoundError, NoSuchMethodError or similar), please check out Troubleshoot dependency version conflict article first. If it doesn't provide solution for the problem, please provide:

• verbose dependency tree (mvn dependency:tree -Dverbose)
• exception message, full stack trace, and any available logs

Additional context
