jgrusewski 7751f7615a fix(ci): unblock CPU service builds and fix H100 BF16 regime classification ...

Three fixes validated by 20/20 hyperopt trials on H100 (zero OOM):

1. Workspace default-features: ml-core, ml-dqn, ml-ppo, ml-supervised
   workspace deps now have default-features=false. Prevents cudarc
   (which requires nvcc) from leaking into CPU service builds via
   Cargo feature unification. CI compile-services was failing with
   "Failed to execute nvcc: No such file or directory" (exit 101).

2. BF16 comparison fix: Candle's gt()/le() don't support BF16 operands.
   Cast ADX/CUSUM features to F32 before threshold comparison in
   regime classification. Previous approach (cast threshold to BF16)
   failed due to Candle broadcast_as reverting dtype.

3. CI pipeline: expand ML change detection to all 14 sub-crates,
   add component:compile labels for sccache network policy matching,
   bump training runtime to CUDA 12.6 + Ubuntu 24.04 (glibc 2.39).
