When filtering commits with grep -v, if all commits are filtered out,
grep returns exit code 1 which causes the pipeline to fail with set -e.
Wrap grep commands in { ... || true; } to ensure they don't fail the
pipeline when they filter out all results.
This fixes the workflow failure when a fix(astrolabe): commit is pushed
without any MCP server changes.
