Subject: [PATCH] feat(forge): port every reconciler call site onto the shim
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Term 1 completed. All 52 runtime gh call sites in the three reconcilers and
lib/ruling.sh now go through forge_* verbs; the three remaining matches in
labels-reconcile are prose in comments. lib/facts.sh is deliberately
untouched — it is the release door, and the ruling keeps release.yml out of
this issue.

The CEREMONY_FORGE_CLIENT:-gh wrappers die here, in the same commit as the
sites they described, so the tree is never in a state where the declaration
lies. main() now runs forge_preflight then forge_select "".

Two sites needed judgment rather than substitution:

  - labels-scope's write is forge_labels_add, a genuine additive POST on
    both backends, NOT forge_issue_edit --add-label. ceremony#128 turns on
    that write not being a read-modify-PUT: the labeler action computed
    (labels-at-job-start union derived) and PUT the whole set, silently
    dropping a label applied while the job ran. Routing it through a generic
    edit verb would have quietly reopened that.

  - the human-review request is forge_request_reviewer. Contrary to my
    earlier reading, POST /pulls/{n}/requested_reviewers DOES exist on
    Forgejo — 422 naming the reviewer's access without it, 201 with it. The
    earlier 404 was a GET, which the endpoint does not serve, plus a
    username that did not exist.

Test churn, all of it the term-5 boundary move:

  - the suites select the github backend, so their existing gh() stubs stay
    the boundary and keep intercepting;
  - stubs strip the paging the shim injects, so fixtures stay keyed on the
    logical endpoint (inlined in the PATH stub, which is a standalone
    executable and cannot see a shell function);
  - fixtures renamed off the per_page suffix for the same reason;
  - recorded-mutation assertions now match the verb, not the raw gh line;
  - gh() stubs carry SC2317: they are reached through the backend now, so
    shellcheck can no longer see the call path.
