chore: push public docs to the soulcraft.com ingest door on release

scripts/push-docs.js collects docs/**/*.md with public:true frontmatter
and POSTs them (batches of 10, idempotent per slug) to the docs ingest
door after npm publish — release.sh step 12. Absent secret = loud skip
(publish already happened; the serving side can interim-sync); a failed
push exits non-zero so the docs site never silently trails npm. The
combined /docs landing index is deliberately NOT pushed per-repo — it
spans both engine corpora and is authored on the serving side.

+ * @module scripts/push-docs
+ * @description Push this repo's PUBLIC docs to the soulcraft.com docs ingest
+ * door after an npm publish (VENUE-DOCS-RELEASE-PUSH — retires the old
+ * build-time docs sync).
+ *
+ * Contract (mirrors the reference implementation on the serving side):
+ *   POST {base}/api/docs/ingest
+ *   headers: x-service-secret: $DOCS_INGEST_SECRET, Content-Type: application/json
+ *   body: { docs: [{ slug, title, markdown, nav: { order, section } }] }
+ *   batches of 10, idempotent per slug.
+ *
+ * A doc is public iff its frontmatter has `public: true` AND a `slug`. The
+ * frontmatter is stripped; `category` → nav.section, `order` → nav.order.
+ *
+ * Deliberately NOT pushed: the combined /docs landing index. It spans BOTH
+ * engine corpora (this repo's and the native accelerator's), so a per-repo
+ * push would clobber the union — the index is authored on the serving side.
+ *
+ * Env: DOCS_INGEST_SECRET (required), DOCS_INGEST_BASE (default
+ * https://soulcraft.com). Exits 0 with a LOUD warning when the secret is
+ * absent (the npm publish has already happened; the serving side runs its
+ * interim sync on request) and exits 1 when a push actually fails — the docs
+ * site would silently trail npm otherwise, and that must be visible.
