Long prompts can make the mock engine skip a matching judge or keyword branch: with pipefail, grep -q exits early and the upstream echo can receive SIGPIPE. This can leave the correction-retry test recording only correction instead of initial\ncorrection\n, as observed in main CI run 40647801009. Retrying that run passed and restored the README CI badge.

Replace the mock's detection pipelines with Bash string matching, preserving case-sensitive judge detection and case-insensitive keyword responses. Add eight 1 MiB prompt regression cases covering initial/correction judge responses and every keyword branch; the old script was reproduced skipping the initial judge branch.

Validation:

• make fmt and make verify (zero issues; pinned tools rebuilt with Go 1.26.0).
• make test through the environment's existing child-reaping wrapper, required because this container's PID 1 does not reap orphan processes; all tests pass.
• make e2e and the focused correction-retry/long-prompt tests pass.
• bash -n and git diff --check pass.
