fix: Smoke test has no coverage for inline-sourced lib files beyond the four listed (#180)

- Add check_script calls for all inline-sourced lib files (agent-session.sh,
  ci-helpers.sh, file-action-issue.sh, formula-session.sh, load-project.sh)
  so their internal function calls are verified
- Add check_script calls for standalone lib scripts (ci-debug.sh,
  matrix_listener.sh, parse-deps.sh) and legacy prediction scripts
- Add documentation comment on LIB_FUNS listing included/excluded lib files
  with rationale for each
