Loki Mode v7.23.1

Fixed

• CI reliability: tests/test-delegate-notify.sh no longer false-fails on a CI
  runner whose git default branch is "master". The test git-inits a temp repo
  and asserted the notification body contained "main", but git init uses the
  host default branch (main on newer git, master on older runners), so the
  assertion failed on the runner even though the product correctly reported the
  real branch. The test now forces a deterministic branch (git branch -m main)
  after the first commit. Product behavior is unchanged; this only de-flakes the
  test. This is what kept the v7.23.0 Tests workflow red on the Shell tests job.
