This PR reduces PCS configuration to one choice: 100-bit or 128-bit.
The code calculates the remaining parameters internally from the padded witness size. Callers no longer choose backend profiles or tune individual parameters.
For reviewers, start with profiles.rs.
This is the main change. It contains both profiles, their calculations, and tests covering every supported witness size.
Most other changes update the prover, verifier, CLI, and tests to use this interface. Some also update OOD sampling, transcript binding, and grinding to support the selected target.
All 72 PCS tests, Clippy, and formatting checks passed.
These are BitZ PCS targets. Spartan security is not dynamic.
