Cannot access tools even when they are installed and trusted

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

Linux 5.10.240-218.959.amzn2int.x86_64 - Amazon Linux 2

Expected behaviour

Uses the tool as expected

Actual behaviour

Says the tool is not installed and gives me instructions to install the tools

Steps to reproduce

Just install amzn-mcp and run q chat --trust-all-tools

Den Bericht auf Amazon Linux 2 reproduzieren, indem amzn-mcp installiert und q chat --trust-all-tools ausgeführt wird, und anschließend das Verhalten vor und nach q doctor und q restart vergleichen. Im Issue werden keine Quelldateien oder Tests genannt; abgeschlossen ist die Arbeit, wenn ein installiertes und vertrauenswürdiges Tool erkannt und ohne fehlerhafte Installationsanweisungen verwendet werden kann.
