Fix Format Check: format FastPowerEnzymeExt.jl (SciMLStyle)

[ChrisRackauckas-Claude]

What

The Format Check / Check Formatting job on main was failing. That job runs the SciML shared workflow SciML/.github/.github/workflows/format-check.yml@v1, which applies JuliaFormatter v2 with SciMLStyle() and fails if any file changes.

Locally reproduced on Julia 1.12 (the "1" channel) with JuliaFormatter v2.8.0:

format(".", SciMLStyle(), verbose=true)  # => false (changes needed)
git diff --name-only                     # => ext/FastPowerEnzymeExt.jl

The only unformatted file was ext/FastPowerEnzymeExt.jl (the @easy_rule macro call argument layout). This PR applies the canonical formatting. Re-running the formatter afterward reports the tree as already formatted (true), so the Format Check will pass. The change is purely cosmetic with no semantic effect.

Note: the other red checks on main are downstream tests (OrdinaryDiffEq.jl, SimpleDiffEq.jl) which are out of scope for this repo's own CI.

Local verification

• julia +1.12 with JuliaFormatter v2.8.0 + SciMLStyle: before = needs change (only this file), after = already formatted.

Status update: this PR is now obsolete and should not be merged.

It reformats ext/FastPowerEnzymeExt.jl with JuliaFormatter v2 SciMLStyle() to satisfy a Format Check / Check Formatting job that ran SciML/.github/.github/workflows/format-check.yml@v1. That workflow has since been replaced on main by SciML/.github/.github/workflows/runic.yml@v1 (the runic / Runic Format Check check), which is green on the current main HEAD.

Verified locally with Runic v1.7.0: Runic.format_string reports every .jl file in the repo — including ext/FastPowerEnzymeExt.jl — as already formatted (no diff). The PR is also CONFLICTING against the current main.

Recommend closing without merge; the format check it targeted no longer exists and the tree is already Runic-clean.
