Angular CLI MCP server integration via Gemini CLI behaves inconsistently (requests have no discernible pattern)

### Command

other

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

MCP requests/invocations against the Angular CLI MCP server are inconsistent across runs, and no meaningful pattern can be identified. Because of this, best-practice requirements cannot be reliably met.

### Minimal Reproduction

- Generate mcp json with 'ng mcp'
- Add Server to Gemini CLI settings.json
- Start Gemini CLI and the Angular MCP server
- In Gemini CLI, write a prompt such as: “Create an Angular 21 Form Signals component and use the Angular CLI MCP server.”
- Observe that outcomes are inconsistent across runs (tools sometimes discovered, sometimes not; invocations sometimes succeed, sometimes fail) with no clear pattern

### Exception or Error

```text
Hallo! I will create an Angular component that uses Signals for form management. First, I need to inspect the existing Angular project to
understand its structure and version.

### Your Environment

```text
Angular CLI : 21.0.3
Node.js : 22.18.0
Package Manager : npm 10.9.3
Operating System : linux x64
```

### Anything else relevant?

_No response_

まず、`ng mcp`、生成された MCP JSON、Gemini CLI の `settings.json`、および `list_projects` リクエストを使って問題を再現します。ツールが正常に検出または呼び出される実行と、ENOENT 失敗が発生する実行を比較します。繰り返し実行するプロンプトとプロジェクトディレクトリ全体で Angular CLI MCP サーバーが一貫して動作すれば完了です。
