jgrusewski 4189da563f feat(dqn-v2): C.6 migrate 4 more controllers to AdaptiveController (Tasks 13-16)

Tasks 13-16 of Plan 1 §4.C.6 — Batch B controller migrations:

- Task 13 (TauController): cosine-annealed Polyak EMA coefficient with
  health-coupled floor.  Mirrors compute_cosine_annealed_tau +
  apply_health_coupled_tau_floor from fused_training.rs/gpu_dqn_trainer.rs.
  Wired at epoch-boundary B2/G3 block in training_loop.rs; per-step
  actuators (set_tau_host, target_ema_update) remain in fused_training.rs.
  8 unit tests.

- Task 14 (EpsilonController): ISV-adaptive exploration epsilon.
  Replaces inline base_floor*(0.5+volatility) block (~10 lines) in
  initialize_epoch_state.  Volatility from ISV[2]; agent.set_epsilon()
  actuator call preserved.  8 unit tests.

- Task 15 (ConvictionFloorController): IQL branch_scales per-sample floor
  scaffolding.  Static 0.1 (SchemaContract slot ISV[36]).  write_output
  writes to ISV[36].  Never fires.  Plan 3 adds ramp logic.  7 unit tests.

- Task 16 (PlanThresholdController): plan activation threshold scaffolding.
  Static 0.5, mirrors the > 0.5f literal in experience_kernels.cu and
  backtest_plan_kernel.cu.  Never fires.  Plan 3 §B.4 wires ISV slot.
  6 unit tests.

All 29 new tests pass.  Cargo check: 8 warnings (unchanged from baseline).
Audit doc updated per Invariant 7.
