Feature Request: Add capability to view raw MCP outputs

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue

### Operating system

macOS 15.5.0 (24F74)

### Expected behaviour

Users should be able to view the raw outputs from MCP (Model Context Protocol) tool calls, allowing them to see the unprocessed data returned by the tools.

When querying data using an MCP, it's extremely important that users be able to see the raw results from the MCP in order to ensure the LLM is not hallucinating numbers.

Cline makes the possible and shows all MCP responses, and that feature alone is pushing me to Cline over Q CLI.

### Actual behaviour

Chat context is not relevant. This is a feature request to improve the ability of humans to detect and correct LLM hallucinations which are a fact of life at this time. In order to be able to use Q for data analysis via MCPs users need to have more visibility into tool responses.

I used to do this by logging to stderr, but when MCP stderr started getting piped to a file it broke that solution and I've been unable to use Q CLI for data analysis since as I have no easy way to cross-check data.

### Steps to reproduce

_No response_

L’issue non indica file, test o punti di ingresso. Inizia tracciando dove vengono rese disponibili nella CLI le risposte alle chiamate degli strumenti MCP e verifica il comportamento attuale di stderr-to-file; il lavoro è completato quando gli utenti possono ispezionare le risposte degli strumenti non elaborate, mentre l’output normale della chat rimane utilizzabile.
