feat: renumber lib reference into 4-pillar anatomy

Renumber the 15 reference docs into pillar groups (recipe -> anatomy):
- 01 Build Recipe (entry), 02 Composition Root
- domains: 10 Layering Rules
- contract: 20 Spec-First Routing, 21 CRUD Template, 22 Auth Integration
- interfaces/infra: 30 Infra Adapters
- UI: 40 UI: Auto-Rendered Admin & Custom Pages (new; @aetoskia packages,
  client template, x- catalog via react-openapi MCP module)
- pipelines: 50 Pipeline Scaffold, 51 Worker & Progress, 52 Human-in-the-Loop
- delivery/meta: 90 Drone Pipelines, 91 Versioning & Changelog,
  92 Genericity Matrix, 93 Library Registry, 94 Repository Inventory

MCP module names are unchanged (NN_ prefix stripped); all cross-references
(wiki, templates, hooks, registry) updated; lib index rewritten pillar-first;
build recipe bootstraps the client template. Bundle + HTML sites regenerated.

+# Repository Inventory
+
+## Summary
+
+The canonical list of Aetos repositories covered by the CI and versioning
+standards, with the artifact each one produces, its version source, and its
+Drone shape. Every entry maps to the contract in
+[91 – Versioning & Changelog](91_versioning_and_changelog.md) and the two CI
+files in [90 – Drone Pipelines](90_drone_pipelines.md).
+
+The same data is published machine-readably as the `registry://repos` MCP
+resource (and the `list_repos` tool), sourced from `standards/src/repos.json`.
+Paths are relative to the `aetos/` workspace root.
+
+---
+
+## Packages (Type A)
+
+A wheel + sdist published to the private index. Version source is
+`pyproject.toml`; Drone file is `python-lib.yaml` (tag-triggered).
+
+| Repo | Path | Docs | MCP server |
+|------|------|------|------------|
+| `dagpipe` | `dagpipe` | lib, wiki | `dagpipe:8006` |
+| `doc-forge` | `doc-forge` | lib, wiki | `docforge:8001` |
+| `hexa` | `hexa` | lib, wiki | `hexa:8008` |
+| `mail-intake` | `mail-intake` | lib, wiki | `mail_intake:8002` |
+| `mongo-ops` | `mongo-ops` | lib, wiki | `mongo_ops:8007` |
+| `omniread` | `omniread` | lib, wiki | `omniread:8003` |
+| `openapi-first` | `openapi-first` | lib, wiki | `openapi_first:8004` |
+| `py-jwt` | `py-jwt` | lib, wiki | `jwtlib:8005` |
+
+---
+
+## Services (Type B)
+
+A container image pushed to the registry and run on the Docker host. Version
+source is the `VERSION` file; Drone file is `service-docker.yaml`.
+
+| Repo | Path | Trigger | Docs |
+|------|------|---------|------|
+| `auth-server` | `auth-server` | tag | api, lib, wiki |
+
+Tag-triggered and enforces `tag == VERSION`.
+
+---
+
+## Required files per repo
+
+| Type | Version source | Changelog | Drone |
+|------|----------------|-----------|-------|
+| package | `pyproject.toml` | `CHANGELOG.md` | `python-lib.yaml` |
+| service | `VERSION` | `CHANGELOG.md` | `service-docker.yaml` |
+
+Every covered repository must be able to satisfy `tag == version`:
+the version file (never a commit id) is bumped in the release MR, the MR is
+merged, and the tag is created on the merged commit.
