Feature request: visible scratchpad folder in the desktop app

Claude Code gives each session an auto-created scratchpad directory, but it's buried in %LOCALAPPDATA%\Temp\claude\<project>\<session-id>\scratchpad with a new session ID every conversation — users can't realistically find it, pin it, or grab files Claude produced there.

Request: surface it in the desktop app UI as a folder icon (top bar or next to the chat) that opens the current session's scratchpad in Explorer/Finder, ideally with a stable per-project scratch location so shortcuts survive across sessions.

Real-world example: Claude generated a test session file in the scratchpad for me to open in another app (Pro Tools), and the only way I could get to it was asking Claude for the full path — which changes next session.
