chore(examples): add explicit --audience agent to codeup_ci and action.yml (#1004)

Since PR #929 made 'human' the default audience and redirected [ocr] progress lines to stderr, the two non-interactive CI call sites that omitted --audience now emit progress noise on stderr. Add --audience agent to match the other four examples.

- examples/codeup_ci/post_review.py: add --audience agent to cmd
- action.yml: add --audience agent to ARGS (also covers github_actions)
- examples/codeup_ci/post_review_test.py: update exact cmd assertion

Exit-code handling, JSON parsing, and comment-posting logic are unchanged.

Closes #1003
