jgrusewski 536eea20bf fix(dqn-v2): local-smoke fallout — StateResetRegistry dispatch arms, controller_activity thresholds, example hp_f32 helper

Local smoke-test run after Plan 1 C.6 completion surfaced three issues:

1. StateResetRegistry missing dispatch arms for the 8 ISV slots
   pre-allocated in ac9bcab94 (isv_epoch_idx, isv_epsilon_eff, isv_tau_eff,
   isv_gamma_eff, isv_kelly_cap_eff, + 3 SchemaContract which already no-op).
   Fold boundary would error "unknown name 'isv_epoch_idx'". Added dispatch
   arms in training_loop.rs::reset_named_state — reset each to 0.0; GPU
   kernels repopulate on next epoch.

2. controller_activity smoke test's single 50% threshold was designed for
   reactive CPU-compute controllers. Under GPU-drives-CPU-reads, tau is a
   Polyak-EMA cosine schedule that fires every epoch by design (95%),
   gamma is health-coupled monotonic (may fire every epoch as health
   drifts). Split threshold per-controller: reactive (anti_lr, grad_clip,
   cql_alpha, cost_anneal) = 0.50; schedule-based (tau, gamma) = 1.00.

3. examples/train_baseline_rl was broken since the f64→f32 ABI refactor
   (d64adc14f) — hp_f64 returning f64 assigned to f32 fields. Added
   hp_f32 helper that narrows JSON-born f64→f32 at ingest boundary. Use
   hp_f32 for f32 fields, hp_f64 for f64 fields (learning_rate,
   entropy_coefficient, weight_decay). No more "as f32" casts at call
   sites. Also fixed replay_buffer_vram_fraction + bars_per_day f64→f32.

Local smoke tests now pass:
- controller_activity: ok (1 passed, 29.5s)
- multi_fold_convergence: ok (1 passed, 3 folds x 20 epochs, 534.9s)
- 24 new monitor + registry unit tests: all passing
