[FEATURE] Unsent draft text is cleared when switching sessions (VS Code Extension)

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

Text typed into the input field in the VS Code extension sidebar is silently discarded when switching to a different session or conversation. There is no warning and no recovery. This creates real friction when working across multiple active sessions.

Proposed Solution

Persist draft text per session in memory (or optionally local storage) so that returning to a session restores whatever was typed but not yet sent. The input field should behave like a per-session draft buffer.

Alternative Solutions

Currently write long prompts in a different application then copy them in once complete.
