Removes the 'if: false' that disabled the (now centralized) Downgrade workflow. The reusable SciML/.github downgrade workflow defaults to allow-reresolve: false, so the suite runs against the minimal (downgraded) dependency versions. Raises the [compat] lower bounds (declared deps only) needed for the floor set to build/pass: Distributions 0.24, 0.25 -> 0.25.88 (resolve floor) StatsBase 0.33, 0.34 -> 0.34.11 (build-skew) Compat 3.27, 4 -> 4.18.1 (build-skew) Verified locally on Julia 1.10 in a clean depot + fresh registry: Pkg.test(allow_reresolve=false) passes at the floor with 0 re-resolve.
