Subject: [PATCH] ci(crow): add weekly patch-proposal + feedback-loop pipeline

Add `.crow/weekly-patch-proposals.yaml`, a single (non-matrix) job that runs
the classifier over all of `single_builds` weekly: it posts/updates a Forgejo
tracking issue with the auto-proposable registry entries via
`propose-patches.R --open-issue`, then logs the step-4 metrics via
`proposal-tracking.R`. Clones read-only; the only write is the issue.
Register the `weekly-patch-proposals` cron in the crow UI, or trigger manually
with `task=weekly-patch-proposals`.

+# Weekly failure-triage proposals (issue #115, steps 3 + 4).
+# Classifies the recorded `single_builds` failures and:
+#   1. posts/updates a Forgejo tracking issue with the auto-proposable registry
+#      entries (human reviews, trial-builds, and opens the PR -- nothing merges), and
+#   2. prints the feedback-loop metrics (signature hit rate, proposed-vs-merged,
+#      retirement candidates) to the run log.
+# Global across platforms (the classifier groups over all of single_builds), so
+# a single job -- no matrix. Clones read-only; the only write is the Forgejo
+# issue via FORGEJO_TOKEN.

+`.crow/weekly-patch-proposals.yaml` runs both steps weekly (register the `weekly-patch-proposals` cron in the crow UI): it posts/updates a Forgejo tracking issue with the auto-proposable entries and logs the feedback-loop metrics.
+It clones read-only; the only write is the tracking issue.
