jgrusewski 5546a45bc3 refactor: remove gpu_n_episodes override — auto-scale from VRAM everywhere
gpu_n_episodes was manually overridden in GPU profiles, training configs,
test files, and hyperopt — all set to 0 or small fixed values that
bypassed the auto-scaling logic, causing a div-by-zero crash in
train_baseline_rl.

Now: single auto-scaling path via optimal_n_episodes() from VRAM/SM
count. No manual override field. Cap at 16384 (consistent with
AutoBatchSizer's 8192 cap pattern). Floor at 32 for small GPUs.

Removed gpu_n_episodes from:
- DQNHyperparameters, PpoHyperparameters structs
- All 4 GPU profiles (rtx3050, h100, a100, default)
- Training profiles (smoketest, localdev)
- ExperienceProfile struct + serde
- Hyperopt adapter
- All test overrides

//! **AGENT 4.4B: Recurrent PPO Performance Tests**
//!
//! TDD implementation of 2 performance tests for Recurrent PPO:
//!
//! 1. **`test_recurrent_ppo_training_speed()`**
//! - Measures training time slowdown (recurrent vs feedforward)
//! - Expects: 1.5-2x slowdown (acceptable range: 1.2-3.0x)
//! - Fails if: >3x slowdown
//!
//! 2. **`test_recurrent_ppo_memory_usage()`**
//! - Measures GPU memory increase (recurrent vs feedforward)
//! - Expects: 20-50% more memory
//! - Fails if: >2x memory increase
//!
//! **Test Strategy**:
//! - Use small configs for fast iteration (5 epochs, batch_size=32)
//! - Train feedforward PPO first (baseline)
//! - Train recurrent PPO second (comparison)
//! - Measure time using std::time::Instant
//! - Measure memory using CUDA memory stats (if available)
//!
//! **Dependencies**:
//! - LSTM infrastructure (10/10 tests passing)
//! - PpoTrainer with LSTM support
//! - Gradient clipping: max_grad_norm_lstm=0.5
