Describe the bug
When a new agent definition file is added to ~/.copilot/agents/ (the user-scoped agent directory), the GitHub Copilot App UI does not pick it up even after opening a new project session. A full app restart is required.
In contrast, the CLI (copilot command) correctly discovers the new agent immediately without needing a restart.
Steps to reproduce
Add a new .md agent file to ~/.copilot/agents/
Open a new project session in the App UI
Click "Default agent" dropdown — the new agent does not appear
Run copilot CLI in terminal and type /agent — the new agent appears correctly
Expected behavior
The App UI should discover user-scoped agents from ~/.copilot/agents/ when a new project session is opened, consistent with how the CLI behaves.
Actual behavior
The agent is not visible in the App UI until the entire app is quit and relaunched.
Environment
GitHub Copilot App version: 1.0.66
CLI version: 1.0.65
OS: macOS
