roast-bot: roast for desertaxle

[devin-ai-integration]

Summary

roast-bot run for desertaxle. No dev-log post from them in the last 7 days, so a roast was written.

• Adds content/blog/roast-desertaxle-cancelled-pending-review.md — a roast of PrefectHQ/prefect#22238 ("Add cancelling timeout cleanup producer"). Angles: the Codex review bot filed a P1 + four P2s + a CodeQL hit (a cancellation "authority" that lets CANCELLED → COMPLETED un-cancel runs; a 200-row "backstop" that never paginates) while the only human review was "looks good to me!"; a validation_alias invented as legacy-compat for a brand-new setting in violation of the repo's own settings/AGENTS.md; and defensive naming churn (maybe_schedule_cancelling_timeout_check_for_state).
• Updates data/roast_bot.json last_run to 2026-07-20T13:07:00+00:00.
