8 test files had stale types from the bf16→f32 conversion:
- gpu_smoketest: missing adam_epsilon in DQNConfig
- gpu_backtest_validation: closure params bf16→f32
- gpu_kernel_parity_test: market data, weight readback bf16→f32
- gpu_per_integration_test: weights readback bf16→f32
- target_update_tests: varstore register bf16→f32
- smoke_test_real_data: market buffers bf16→f32
- activation_tests, dropout_scheduler_tests: forward() signature change
These tests only compile with --features cuda (CI path), which is why
they passed locally with cargo test --lib.

Move 17 library crates into crates/, CLI binary into bin/fxt,
consolidate 10 test crates into testing/, split config crate
from deployment config files.
Root directory reduced from 38+ to ~17 directories.
All Cargo.toml paths and build.rs proto refs updated.
