cluade-reviewer-andresmgsl 21c70e06a4 fix(forge): an empty REPO cannot become a fact, and the backend verbs are tested
Both panel blockers on c63a550.

@kimi found the one that mattered: facts.sh got the REPO fix, release.yml's
own four call sites did not. A workflow `run:` shell carries no `set -u`, so
an unset REPO expands empty and the verb addresses `repos//…` — which 404s,
and the 404 is then read as an ANSWER. Reproduced read-only against this
instance before fixing:

  forge_release_exists 0.4.1   -> "no", rc 0
  forge_commit_pulls 7fc9afe4  -> "[]", rc 0    (the !189 merge, which HAS a
                                                 merged PR behind it)

The first would have let the nothing-exists assert proceed to CREATE; the
second is the drill's original fabricated `labeled=no`, one step after the
fix meant to kill it.

Fixed once rather than at four call sites, as kimi suggested: forge_select
defaults REPO from GITHUB_REPOSITORY, and forgejo_api_base — which every
verb reaches the network through — refuses an empty REPO outright. No fifth
call site can forget it.

@grok and @kimi both blocked on the same AC gap: the backend suite did not
cover the five new verbs, so the two measured asymmetries had no offline
coverage. test/forge-backends.test.sh now has 15 cases for them — singular
/pull wrapped to an array, 404 as an empty array, 500 refusing, release
present/absent/unreadable, POST /tags vs /git/refs, the publish body, and
the REPO-empty must-fail. Mutation-checked: reading the plural path fails
one case, dropping the REPO guard fails the two must-fails.

1029 assertions, 22 suites, shellcheck-all and actionlint clean.

### Fixed
- The release doors run on a Forgejo consumer. `lib/facts.sh` and
`release.yml` gathered and published through `gh`, which the runner image
does not ship, so the merge door read `labeled=no` for a correctly
labeled ceremony PR and the tag door died at the publish (#191).
- A release fact that could not be read is no longer reported as a definite
`no`. A completed read finding no label is still `no` and still
fail-closed; a read that did not complete refuses and emits no fact
(#191).
### Added
- `forge_release_exists`, `forge_commit_pulls`, `forge_tag_create`,
`forge_release_create` and `forge_pr_create` on both backends, so the
release path names no client (#191).
- The forgejo backend serves one PR object at `/commits/{sha}/pull` where
GitHub serves an array at `/pulls`; both verbs emit the array shape, so
the call site carries one expression (#191).
- Forgejo creates tags at `POST /tags` — it serves `/git/refs` GET-only,
so GitHub's ref-POST would have 404'd there forever (#191).
- `forgejo_api_base` refuses when `REPO` is empty. Every verb interpolates
it and every call reaches the network through there, so `repos//…`
whose 404 reads as "no release" and "no PRs" — is now impossible (#191).
