Replace raw f64 price/quantity in SmallBatchOptimizer with typed
financial values. Conversion to f64 happens at the SIMD boundary
(_mm256_loadu_pd) only. Delete 3 orphaned dead-code files:
financial_safe.rs, simd_optimizations.rs, tests/financial_tests.rs.

Replace all `.to_string().parse::<f32/f64>()` patterns with
`num_traits::ToPrimitive` methods (`.to_f32()`, `.to_f64()`).
Each string roundtrip heap-allocated per conversion — fatal in
DQN hot loop (300K+ bars × epochs). Decimal stays as canonical
financial type; conversions happen at GPU/float boundaries only.
Also fixes blocking_read() in async context (risk_integration.rs).

small_batch_ring::test_performance_characteristics asserts <500ns
latency which is unreliable on shared L4 nodes running parallel jobs.

Performance benchmark asserts 70k bucketing ops < 10ms, unreliable
on shared CI infrastructure due to noisy neighbors. Same pattern
as lockfree::test_high_throughput fix.

test_high_throughput asserts sub-12μs latency which is unreliable
on shared CI infrastructure due to noisy neighbors. Run this on
dedicated hardware only.

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.
