Description
Type: Bug
Issue: Prompt file not highlighted or sent as context in Agent mode
Problem
In Copilot Agent mode, inserting a prompt file with / only shows the file name as plain text (no highlight), and only the file name—not its content—is sent as context. This makes prompt files ineffective and hard to identify.
Expected
Prompt file names should be highlighted in the UI.
The actual content of the prompt file should be sent as context, not just the file name.
