Cannot list saved conversations to load

### 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
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.7.0 (24G222)

### Expected behaviour

I previously used "/save" on a conversation, but I do not recall what name I have it. The system keeps saying that I can use "/load" with parameters to list saved conversations, but then gives an error when I try that. If it cannot list what is saved, then saving does not help much.

### Actual behaviour

> The /save command saves your current conversation to local storage so you can resume it later.

Basic usage:
• /save - Saves the conversation with an auto-generated name
• /save - Saves the conversation with a specific name you provide

Loading saved conversations:
• /load - Shows a list of saved conversations to choose from and loads the selected one

Storage location:
Conversations are saved locally in your file system and persist across Q CLI sessions.

Example:
> /save my-project-discussion
Conversation saved as "my-project-discussion"

> /load
? Select a conversation to load:
❯ my-project-discussion
previous-chat-session
debugging-help

The save/load functionality lets you maintain multiple ongoing conversations and switch between them as needed.

> "/load" by itself does not do this: "Shows a list of saved conversations to choose from and loads the selected one" it only gives error

> You're correct. I apologize for the inaccuracy in my previous response.

Looking at the documentation, I can see that /save and /load commands are listed in the built-in help, but the specific behavior of /load when used without
arguments is not documented in the available Q CLI documentation.

The documentation only confirms that:
• /save - Save the current conversation
• /load - Load a previous conversation

The exact interface and behavior of /load when used alone (whether it shows an interactive list, requires arguments, or gives an error) is not specified in the
available documentation.

Reference: https://github.com/aws/amazon-q-developer-cli/blob/main/README.md

> so where did you get this example from: "
> /load
? Select a conversation to load:
❯ my-project-discussion
previous-chat-session
debugging-help"

> You're absolutely right to call that out. I generated that example based on assumptions about how the /load command might work, rather than from the actual Q CLI
documentation.

The documentation I have access to only lists /load as "Load a previous conversation" without providing any details about its specific behavior, interface, or
examples.

I should not have created that fictional example. The correct response is that the specific behavior and usage of /load is not documented in the available Q CLI
documentation.

### Steps to reproduce

/save xxx
/quit
>q chat
/load

Inizia in q chat riproducendo i passaggi documentati: /save xxx, /quit, riavvia q chat, quindi /load. Traccia la gestione del comando /load e del relativo argomento PATH obbligatorio; il lavoro è completato quando gli utenti possono elencare e selezionare le conversazioni salvate invocando /load senza un percorso, con una copertura dell’errore segnalato.
