Split NATS modules: splitter, WORM bloom archive, aggregator, docs-master

Each module has SUMMARY.md and NATS.md (who sends/receives, subject
addresses, payload). Tests: splitter 3, worm 3, aggregator 2.
Forgejo repos pushed separately; this commit keeps them in the monorepo.

+# verae-request-splitter
+
+**Job:** Peel a request into (1) chain hash and (2) off-chain archive puts.
+
+**Expects messages from:** middleware-http (in-process call today; later NATS `verae.splitter.in` if split out).
+
+**Sends messages to:**
+- Chain path: `{ sha256, hashAlg, data? }`
+- `verae.archive.put` for each `publicMeta` / `privateMeta` / `file`
+
+**Does not talk to Zapier or NATS job poller.**
+
+**Test:** `npm test` — hash-only has zero puts; two files + public meta → 3 puts.
