Fix devcontainer credential forwarding and permission issues

- Add ~/.claude mount to devcontainer.json for IDE users (VS Code
  "Reopen in Container" now gets Claude credentials)
- Add updateRemoteUserUID to fix UID mismatch between host and container
- Fix wl-session-restore path in wl mux (use absolute path since
  bash -c doesn't source .bashrc)
