uninstall.sh: the credential error message never shows because of set -e #132

uninstall.sh L52-53:

sts_output=$(aws sts get-caller-identity 2>&1)
sts_rc=$?

Problem: The script uses set -euo pipefail (L7). When credentials are missing or expired, the assignment fails and the script stops at once with exit 1. The lines that show sts_output and the "Run 'aws configure' first" hint never run, so the user sees no message.

Fix:

local sts_output sts_rc=0
sts_output=$(aws sts get-caller-identity 2>&1) || sts_rc=$?
