Document every repo in Sphinx, catalog PDFs, and verae-ops

Add missing package READMEs, expand Sphinx to all runtime modules,
publish a LaTeX/PDF README book, and add verae-ops for Docker,
Proxmox, VMs, dedicated hardware, and service linking. Catalog
defaults to public PDF links for each module README and samples.

+# verae-request-splitter
+
+Splits a Zapier/middleware body into (1) the **chain hash** and (2) off-chain **archive puts**. File bytes never go on `api.veraetime.net`.
+
+**Forgejo:** https://git.georgelambert.org/marchon/verae-request-splitter  
+**Catalog:** https://zapier.georgelambert.org/packages/verae-request-splitter/README.pdf  
+**NATS:** https://zapier.georgelambert.org/docs-master/modules/verae-request-splitter/NATS.pdf
+
+## Run
+
+```bash
+cd packages/verae-request-splitter
+npm test
+```
+
+Today middleware calls this **in-process**. A later split-out can subscribe `verae.splitter.in`.
+
+## Outputs
+
+| Path | Content |
+|------|---------|
+| Chain | `{ sha256, hashAlg }` only |
+| `verae.archive.put` | each `publicMeta` / `privateMeta` / `file` |
+| Batch | Merkle **root** on chain; leaves → tree-node puts (`kind=tree`) |
+
+## Depends on
+
+- middleware-http (caller)
+- archive-worm / tree-node (puts)
+- chain client (hash seal)
+
+Does not talk to Zapier or the job poller.
