Keep shared MCP types stable in Code Mode exec descriptions (#50536)

Browse Source 
## Why

Changing a deferred tool's output schema could add or remove the shared MCP type preamble from the `exec` description.

## What changed

Include the default or configured MCP TypeScript preamble whenever `code_mode_only` is enabled, regardless of the available tools' output schemas. Preserve an empty preamble override as a way to omit the section.

## Testing

Add a regression test that checks description stability when a deferred tool gains an MCP output schema, covering default, custom, and empty preambles. Update description expectations, request snapshots, and two Guardian context-budget test thresholds for the added preamble.
