chore(porch): bugfix-298 state commits stranded after #300 merged

[pseudoseed]

Summary

porch done bugfix-298 --merged 300 writes its state commit after the PR merges, so the
commit lands on a branch nothing will pull. #300 is merged and this one entry never reached
main.

Refs #233

What is in it

One commit, one file, three lines:

2ae42073b chore(porch): bugfix-298 PR #300 merged
 codev/projects/bugfix-298-the-npm-pack-test-walks-the-li/status.yaml | 4 +++-

origin/main is merged into the branch first, so the diff against main is exactly that file
and nothing else.

Test Plan

• git diff origin/main..HEAD --stat shows one file, 3 insertions, 1 deletion
• No source, test or documentation change — porch state only
