docs: remove stale complete.md and fix remaining stale references (#1522)

Deletes `complete.md` and cleans up the last references to the
pre-restructuring docs layout.

## Why `complete.md` goes

It is 2,944 lines (31% of all documentation lines in the repo)
self-described as *"all documentation from the docs/ directory compiled
into a single markdown file"*. But:

- **No generator exists.** No make target, no workflow, no script. `grep
-rn "complete\.md"` finds **zero** references anywhere in the repo.
- **It mirrors a docs tree that no longer exists** — `docs/guides/`,
`docs/explanations/`, `docs/concepts/`.
- **All 72 of its relative links are broken**, and six of the basenames
it references exist nowhere in the repo.
- **~14 current docs are missing from it entirely** (`about.mdx`,
`authentication.mdx`, `package-types.mdx`, both CHANGELOGs, ...).
- **Its `server.json` examples pin the superseded `2025-07-09` schema**
(current is `2025-12-11`).

The strongest argument is its own last commit. [PR
#1278](https://github.com/modelcontextprotocol/registry/pull/1278)
closed [issue
#767](https://github.com/modelcontextprotocol/registry/issues/767) — a
real user-reported CLI flag bug — by editing **only `complete.md`**. A
genuine fix landed in a file nobody reads, while the docs a reader would
actually find stayed wrong.

A generated file with no generator degrades into a trap: authoritative
enough that people edit it, with nothing validating it. If the
LLM-consumption use case is worth keeping, the right shape is a `make
docs-bundle` target plus a `check-docs-bundle` CI job mirroring the
existing `check-schema` pattern — happy to do that instead if you would
rather keep it.

## Remaining stale references

| File | Was | Now |
|---|---|---|
| `contributing/add-package-registry.md` | Add
`docs/guides/publishing/publish-[yourregistry].md`, update
`docs/guides/publishing/README.md` | Add a section to
`package-types.mdx`. These were the **last live references** to the
obsolete `docs/guides/` layout outside `complete.md` |
| `administration/maintainer-onboarding.md` | Add them to "Current key
maintainers" in README | "Registry Working Group" — the section that
actually exists |
| `reference/README.md` | Omitted 6 reference docs | Adds
`api/extensions.md`, `api/openapi.yaml`, `api/CHANGELOG.md`,
`server-json/CHANGELOG.md`, `server-json/CONTRIBUTING.md`,
`server-json/draft/` |
| `docs/README.md` | Index omitted `community-projects.md` | Listed |
| `reference/api/generic-registry-api.md` | `PUT .../versions/{version}`
"not implemented by official registry" | It **is** implemented
([edit.go:36](https://github.com/modelcontextprotocol/registry/blob/main/internal/api/handlers/v0/edit.go#L36)),
and `official-registry-api.md` already lists it as an admin endpoint |
| `reference/api/official-registry-api.md` | Omitted 3 registered routes
| Adds `POST /v0.1/validate` (which `mcp-publisher validate` calls),
`GET /v0.1/ping`, `GET /v0.1/version`, and notes these plus `/health`
are absent from `openapi.yaml` |
| `server-json/official-registry-requirements.md` | Per-registry
verification → `quickstart.mdx` | → `package-types.mdx`, which has an
Ownership Verification section per registry |
| `design/design-principles.md` | Sections 1,2,3,4,**6**,7 | Renumbered
1–6 |
| `contributing/releasing.md` | Steps 1,2,3,**5**,6 | Renumbered 1–5 |

I left the sibling `DELETE` claim in `generic-registry-api.md` alone —
it is accurate, no DELETE route is registered (the `http.MethodDelete`
hit in `server.go` is CORS config, not a route).

## Staleness banners rather than rewrites

**`design/tech-architecture.md`** is substantially fictional. Rather
than a vague "may be outdated", the banner lists what I verified is
wrong:

- Describes Helm-chart deployment; the registry is a plain `Deployment`
([registry.go:65](https://github.com/modelcontextprotocol/registry/blob/main/deploy/pkg/k8s/registry.go#L65)).
Helm is used only for third-party components.
- Diagram shows a `StatefulSet` on port **27017** — MongoDB's port. The
DB is PostgreSQL on 5432 via the CloudNativePG operator.
- Documents a `verify-domain` challenge flow (`POST /verify-domain`,
`/verify-domain/check`, server-issued tokens) that **was never built**.
- Documents `/admin/*` routes that are not registered.
- Says the DB stores user auth state and DNS verification records; only
`servers` and `server_extensions` tables exist.

**`design/roadmap.md`** still says "Phase 1: MVP/Go-Live (Current
Focus)" ~11 months after launch. I added a dated note rather than
inventing a current phase — that is a working-group call.

## Verification

All **101** remaining relative links across every `.md`/`.mdx` in the
repo resolve. The only two non-resolving matches are the intentional
`[project-name](link)` template placeholder and the moderation link
fixed in #1518.
