jgrusewski 4a48e99a48 feat(dqn-v2): C.6 Task 17 — grad_balancer CPU monitor ...

Adds CPU-side read-only GradBalancerMonitor for the existing
`grad_balance_isv_update` GPU kernel. Monitor reads ISV slots 31-35
(GRAD_NORM_TARGET_{DIR,MAG,ORD,URG}_INDEX + GRAD_SCALE_LIMIT_INDEX);
returns mean-of-4-targets as the representative scalar; exposes all 5
slots + mean + fire-rate via diagnose().

Creates the `trainers/dqn/monitors/` module directory. Subsequent tasks
add kernels + monitors for atoms, gamma, kelly_cap, tau, epsilon.

Tests: 3 unit tests pass (read returns mean, diagnose exposes 7 fields,
observe tracks fire-rate with 1e-6 epsilon).

No behavioural change — kernel unchanged, monitor is pure observer.

Plan 1 Task 17. Spec §4.C.6 (2026-04-24 revision).
