enable inclusive thermal rates through shared vacuum machinery

Remove thermal-only process and UV restrictions and replace the capped
signed-root solver with general radial interval isolation. Reuse the
existing real-virtual, raised-residue and UV renormalization paths.

Restore scalar and QCD benchmarks with independent references, current
integration records, and documented numerical convergence limits.

Validation: 116 selected tests, relevant Clippy, CLI/settings reference
check, and documentation renders passed. Completed current integrations
cover 1.3 million process evaluations with no final sample failures.
