jif fcc4ca552f Preserve longer MCP source descriptions in tool search (#37066) ...

## Why

The 4 KiB aggregate limit can truncate source metadata before it reaches the
model through the tool search description.

## What changed

Raise the aggregate source-description limit to 512 KiB while retaining the
existing character-boundary-safe truncation and bounded output.

## Testing

Expand unit and RMCP round-trip coverage to verify that substantially longer
Unicode descriptions remain complete within the new limit.
