Add queue-planning helpdesk routing mechanics

 The project uses a queue-based episode model.
 
 - `reset()` samples a task and a queue of 3 to 5 tickets
-- `step()` grades one ticket submission at a time
+- `step()` lets the agent investigate or submit one ticket at a time
 - `state()` exposes the internal episode snapshot

+- hard-task episodes also track queue-level capacity, alternate acceptable routes, and planning penalties across tickets
+- final evaluation is based on the queue outcome, not on isolated per-ticket classification alone

 ## Lightweight Policy Improvement Loop

+The repo includes a local policy runner in `policy_learning.py`. It still does not update model weights, but it now does more than cosmetic search: it evaluates repeated seeded rollouts, learns cue-conditioned tool preferences for investigation, uses the same planning-aware deterministic submit logic as `inference.py`, and ranks policies by terminal rubric reward first, with lower planning penalty as the tie-breaker.
