refactor: CLI binaries use shared fxcache::discover_and_load()

Browse Source 
Replace 40-line inline fxcache discovery block in train_baseline_rl.rs
with a single call to ml::fxcache::discover_and_load(). precompute_features.rs
already uses correct symbol/data_source args — no changes needed there.
