test(bots): TEMP engineer-bot e2e verification workflow (DO NOT MERGE)

Verifies the engineer author path on the PR branch (poetry install, .bot config
load, prompt resolution, author agent) since issues/workflow_dispatch triggers
only register from main. Author-only, no publish, fixed test issue #864.
Removed before #862 is finalized.

+# TEMPORARY — engineer-bot end-to-end verification (DO NOT MERGE; removed before finalize).
+#
+# The real engineer-bot.yml triggers on issues/workflow_dispatch, which only
+# register from the default branch — so they can't run on this PR branch. This
+# pull_request-triggered clone exercises the engineer AUTHOR path on the branch:
+# poetry install, .bot/config.yaml load, prompt resolution, and the author agent.
+# It runs AUTHOR ONLY (no publish) against a fixed throwaway issue (#864), so it
+# cannot open a spurious fix PR. Delete this file before marking #862 ready.
