Angad Singh 1bfabb21fe Raise the MCP tool name limit to 128 bytes (#39594) ...

## Why

The Responses API accepts tool names up to 128 bytes, but MCP tool name
normalization limited model-visible names to 64 bytes.

## What changed

- Preserve MCP tool names up to the 128-byte Responses API limit.
- Continue shortening and hashing names that exceed the limit so generated
  names remain bounded and unique.

## Testing

- Cover names at the 128-byte boundary and immediately above it.
- Verify distinct long names remain 128 bytes and code-mode compatible.
