+- `stk_pending_retry()`: replaced per-module `realloc` at `attempt_load` with a single bulk allocation upfront (`module_count + stk_pending_count`) before the retry loop.
+- `stk_poll()`: replaced per-module `stk_pending_add()` calls inside the unload and cascade loops with batch collection followed by a single `stk_pending_add_batch()` call after each loop.
