/**
|
|
* The pre-install manifest preview — MCPPREV-001 to MCPPREV-005.
|
|
*
|
|
* This is what the admin dialog renders before anything is installed, so a
|
|
* capability the preview drops is a UI section that silently never appears.
|
|
* The MCP tool list has to survive the trip, because reading that text before
|
|
* granting mcp:tools is the entire point of declaring tools in the manifest.
