Six more findings from CodeRabbit and Copilot on #934. All valid; four were
my own docs lagging the write-checking change in d0626f5.
check_forward() now discovers example packs recursively, so a pack nested
under examples/<group>/ can't slip past the "every example pack" contract.
Taken WITHOUT the suggested is_file() filter, which would have broken it: a
feedpak is dual-form — a zip (foo.feedpak) or a directory (foo.feedpak/) —
and the spec's own examples ship as directories, so is_file() would have
matched zero packs. Suffix matching covers both forms.
load_exceptions() rejects duplicate keys instead of silently keeping the
last one, which would quietly retarget the tracking issue for a piece of
debt this file exists to track.
The sloppak import is wrapped so a missing dependency produces a CI-legible
::error:: rather than a bare traceback.
Docs caught up with the code: the exceptions file header, its stale-entry
rule, and the changelog all said "reads" when the gate checks reads AND
writes.
