Introduce serverId, rename id to versionId (#465)

Browse source 
Wielded Claude Code to do this; across many iterations and have reviewed
all the code + largely rewritten the PR commentary here.

This PR implements the server ID consistency changes from
[#396](https://github.com/modelcontextprotocol/registry/issues/396). Our
goal is to:
- Rename `id` to `versionId` to make it clear that it is the ID for a
specific version, not a server
- Introduce `serverId` as a net new concept. This will be 1:1 with
`name`. While not strictly necessary (we could just use name as a PK),
the convention of having a UUID as an ID on our objects is just a
helpful subjective architecture decision. Plus also leaves open the door
to reconsidering the "should we allow renames" question.

## Key Changes

### 🗄️ Database Schema Changes
- **Renamed**: `id` column → `version_id` (unique identifier for each
server version)

### 📋 Metadata Structure Updates
- **JSON Schema**: Updated
`_meta.io.modelcontextprotocol.registry/official` to include:
  - `serverId`: Consistent ID across all versions of a server
  - `versionId`: Unique ID for this specific version (renamed from `id`)

### 🔧 API Endpoint Updates
- **New endpoint structure**: Changed from version-ID-based to
server-ID-based URLs:
  - `GET /v0/servers/{server_id}` - Get latest version of server
  - `GET /v0/servers/{server_id}?version=X.X.X` - Get specific version  
- `GET /v0/servers/{server_id}/versions` - List all versions of a server
  - `PUT /v0/servers/{server_id}?version=X.X.X` - Edit specific version
- **Consistent URL patterns**: All server endpoints now use `server_id`
as the primary identifier
 
### Database Migration Strategy
The migration (`005_add_server_id_rename_version_id.sql`):
1. Adds new `version_id` column  
2. Generates deterministic UUIDs for servers with the same name
3. Updates JSON metadata to add `serverId` and rename `id` to
`versionId`
4. Copies existing `id` values to `version_id` column
5. Drops old `id` column and makes `version_id` the new primary key

## Testing

Besides of course automated tests passing, I:
1. Set up my local db with the pre-005-migration state, imported all the
production data
2. Ran the migration
3. Spot checked some diffs of the data that resulted --

```json
// before
{
  "name": "io.github.ruvnet/ruv-swarm",
  "_meta": {
    "io.modelcontextprotocol.registry/official": {
      "id": "0a9cda7f-2b73-4839-844b-6582f335de42",
      "is_latest": false,
      "updated_at": "2025-09-10T17:21:34.92137012Z",
      "published_at": "2025-09-10T17:15:32.69690433Z"
    }
  },
  "version": "1.0.18",
  "repository": {
    "url": "",
    "source": ""
  },
  "description": "Neural network swarm orchestration with WebAssembly acceleration and MCP integration"
}

// after
{
  "name": "io.github.ruvnet/ruv-swarm",
  "_meta": {
    "io.modelcontextprotocol.registry/official": {
      "serverId": "e8538952-96af-4a33-9e31-7fbed012521e",

  "repository": {

  "description": "Neural network swarm orchestration with WebAssembly acceleration and MCP integration"

```

Servers that have multiple versions stayed consistent in their
`serverId`:

```json
// First version
{
  "name": "app.getdialer/dialer",
  "_meta": {
    "io.modelcontextprotocol.registry/official": {
      "serverId": "80f08bdb-f3e4-4f19-b072-1676ae49b663",
      "is_latest": false,
      "versionId": "04f25b17-331d-48d7-b08b-37baece208a7",
      "updated_at": "2025-09-09T00:16:49.162620072Z",

    },

    }
  ],
  "version": "1.0.0",
  "repository": {
    "url": "",
    "source": ""
  },
  "description": "An MCP server that provides your you make outbound phone calls using your own phone number"
}

// Second version
{
  "name": "app.getdialer/dialer",
  "_meta": {
    "io.modelcontextprotocol.registry/official": {
      "serverId": "80f08bdb-f3e4-4f19-b072-1676ae49b663",
      "is_latest": true,
      "versionId": "faa26cb9-3aad-415e-aece-f715fff5fe5e",
      "updated_at": "2025-09-09T00:16:49.107842808Z",
      "published_at": "2025-09-09T00:16:49.107842808Z"
    }
  },
  "status": "active",

  "remotes": [

}
```

And I also tried publishing a test server anew; looked good:
