felixxia-oai 51316ead4a [codex] Dedupe plugin MCPs by app declaration name (#27607) ...

## Context

This is the next step in the plugin auth-routing stack. The earlier PRs
make `PluginsManager` auth-aware and move the broad App/MCP surface
decision into that layer. This PR narrows the ChatGPT/SIWC behavior so
we only hide a plugin MCP server when it conflicts with an App
declaration of the same name.

In product terms: if a plugin exposes both an App route and MCP route
for `foo`, ChatGPT/SIWC sessions should use the App route for `foo`. If
the same plugin also exposes a separate MCP server like `foo2`, that MCP
server should remain available.

```json
// .app.json
{
  "apps": {
    "foo": {
      "id": "connector_abc"
    }
  }
}
```

```json
// .mcp.json
{
  "mcpServers": {
    "foo": {
      "url": "https://mcp.foo.com/mcp"
    },
    "foo2": {
      "url": "https://mcp.foo2.com/mcp"
    }
  }
}
```

## Stack

- PR1: #27652 seed plugin manager auth at construction.
- PR2: #27459 route plugin surfaces by auth mode.
- PR3: #27607 dedupe plugin MCP servers by App declaration name.
- PR4: #27602 preserve plugin Apps in connector listings.
- PR5: #27461 skip install-time plugin MCP OAuth for matching App
routes.

## Summary

- Preserve App declaration names in loaded plugin metadata.
- Keep public effective App outputs as deduped connector IDs for
existing callers.
- For ChatGPT/SIWC, suppress only plugin MCP servers whose names match
declared App names.

## Validation

cargo fmt --all
