…-cwd files The Bash tool creates /tmp/claude-*-cwd temp files to track working directory state across commands but never deletes them. This causes hundreds to thousands of orphaned files to accumulate over time (issue anthropics#8856). Add a new tmp-cleanup plugin with a Stop hook that removes these files when a session ends cleanly. Files from crashed/interrupted sessions are collected on the next normal exit.

Addresses #8856.
Every Bash tool invocation creates a
/tmp/claude-{hex}-cwdfile to track the working directory, but these are never cleaned up. Heavy users end up with hundreds or thousands of orphaned files in/tmp.This adds a small
tmp-cleanupplugin that hooks into theStopevent to delete all/tmp/claude-*-cwdfiles when a session ends normally. Files left behind by crashed sessions get picked up on the next clean exit.The plugin is minimal — one Python script, one hook config — and never blocks the stop event even if cleanup fails.
