ci: add Forgejo CI workflow (mirror text-extract)

The six gates the rest of chain-modules already runs against:
fmt-check, clippy with -D warnings, host build, host test,
release wasm32-wasip2 build, plus the manual external-URL
checkout and chain-module-sdk insteadOf URL rewrite (via
secrets.MODULE_SDK_PAT) so cargo can reach the org-private SDK
git dep through Forgejo's REQUIRE_SIGNIN_VIEW.

Same template as text-extract's .forgejo/workflows/ci.yml; the
only swap is the module-name string in the checkout step.
