include CI failure details in Ralph CLAUDE.md for ci-fix tasks

Previously Ralph only saw the PRD user stories for CI fixes but not
the actual failure logs. If the PRD-generating Claude didn't capture
enough detail, Ralph had no way to diagnose the failures.

Now for ci-fix tasks, the raw CI failure details (failed checks, job
names, and log output) are appended directly to Ralph's CLAUDE.md.
Also instructs Ralph to use fix(ci): commit prefix which aligns with
the loop prevention check in check_pr_has_ci_failures.
