refactor: drop the unused pearl--cache-issues variable

The variable was only ever declared and set to nil in pearl-clear-cache — never populated or read anywhere. I removed the defvar, the clear-cache line, and the stale "issues" mention in that docstring. No behavior change; the suite stays at 353 green.
