### Title

**Regression: Local workspace session shows an active terminal but exposes no shell or file-editing tools**

### Description

In a local Git repository session, the terminal panel is open and active, but the agent cannot interact with it or access workspace files. The available toolset does not include shell execution, file reading/writing, patching, canvas actions, or session renaming.

### Steps to reproduce

1. Open a local Git repository in Copilot.
2. Start a branch workspace session.
3. Open and activate the terminal panel.
4. Ask the agent to inspect files, create an application, and run it.
5. Retry after the agent reports missing tools.

### Actual behavior

- The terminal is visible and marked active, but the agent cannot send commands to it.
- Tools such as `shell`, `view`, `apply_patch`, and canvas actions are unavailable.
- The UI requests that the agent rename the session, but `rename_session` is also unavailable.
- Retrying does not restore the tools.
- The agent is limited to skills and session SQLite, making repository work impossible.

### Expected behavior

A local workspace session should automatically expose shell and file-system tools. An active terminal canvas should also be controllable by the agent.

### Environment

- GitHub Copilot CLI/App version: `1.0.69 - 1.0.last`
- OS: macOS (Darwin)
- Workspace type: local branch workspace
- Branch: `main`
- Terminal panel: open and active
- Project session ID: `0d327c01-25e8-42f2-9bb4-9999cc64a643`

### Impact

This completely blocks coding tasks because the agent cannot inspect, modify, run, or validate repository files.

使用报告的 Copilot App 版本，在 macOS 上的本地分支工作区中复现该故障，并确保终端面板已打开且处于活动状态。追踪 shell、file-system、patching、canvas 和 session-renaming 工具缺失的原因；当活动工作区提供预期的工具，并且可以检查、修改、运行和验证仓库工作时，即表示完成。
