[FEATURE] Local storage in the ~/.claude dir of feedback sent via the /feedback command

Preflight Checklist

Problem Statement

There seems to be no local reference created when feedback is sent via /feedback. I assume the input may be captured in session data, however, that data is "up for grabs" & is not persistent if the user decides to delete it. It's also not very convenient for a user to have to search through the session data (which is organized for Anthropic to analyze or for Claude to use, not for a user to find feedback submissions).

Proposed Solution

It seems like it would be quite easy since the logging system is extremely robust for there to be a dir in ~/.claude where atomic uses of the /feedback command could be logged per use.

Alternative Solutions

I have not tried searching the session data but frankly I don't think I should have to work that hard to see my submissions. I think it's a miss that /feedback is not separately logged. A parallel example would be the Feedback Assistant.app on macOS - there is an email like UI for every submission & response.

Priority

Medium - Would be very helpful

Feature Category

File operations

Use Case Example

Example:

1. invoke /feedback
2. complete.
3. A file or folder with a unique identifier / timestamp should be created automatically in a folder in ~/.claude where a user can see the submissions.

Additional Context

Thank you. This is an excellent issue template.
