Summary
CI `changes` pre-flight job intermittently fails with exit 128 when `origin/$base` ref isn't fully fetched (shallow-clone race / fresh runner). `git diff origin/$base...HEAD` then exits non-zero; `bash -e` propagates and fails the whole workflow.
Root cause
`set -e` from `bash -e` causes the command-substitution `changed=$(git diff ...)` to abort on non-zero exit even with `2>/dev/null` redirecting stderr. Append `|| true` so failure falls through to the existing "treat as code-changed" default.
Test plan
Reproduced flake on PRs #347 + #357.
