[FEATURE] Add support to export a session chat

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I often want to document what I have learnt about a repository/project/codebase with Claude code's help.
It also happens often that until I reach 10th question in the conversation, I forgot about first answer.
It would be great if we have an option to export chat conversation to .pdf/.MD etc. so that it can be shared and/or referred later.

Proposed Solution

There should be a slash command like /export <path-to-output-folder> --format [pdf, md, ..] to be run from within a active session.

Alternative Solutions

Currently possible workarounds are as follows:

1. Terminal output capture with output redirection
2. Copy & paste from terminal. This gives raw/unformated content
