What changed and why

Apply Runic 1.10's canonical formatting to the three files that currently fail the repository-wide format check. This is a mechanical-only change: it normalizes comprehension indentation and the Float32 literal spelling, with no behavior or documentation changes.

Please ignore this PR until it has been reviewed by @ChrisRackauckas.

Root cause

The hosted Runic failure reproduces locally on a clean current-main checkout. With the CI version, Runic 1.9.0, git bisect passes at a7b882b466d17c20bcb31cf5367a317bb63430e6 and identifies 44fbfc9192d77aad76ee92103a02bd5704647a62 (#169) as the first failing commit; that commit introduced the non-canonical 2f0 spelling. Current Runic 1.10 additionally canonicalizes two older comprehension layouts, so this PR formats all three files reported by the repository's unpinned major-1 formatter check.

Failing before

On clean current main with Runic 1.9.0:

$ julia +release --project=../.tmp/runic19-env -m Runic --check --diff .
diff --git a/test/reflect.jl b/test/reflect.jl
@@
-            b = a + 2f0 .* randn(Float32, size(a))
+            b = a + 2.0f0 .* randn(Float32, size(a))
# exit 1

With current Runic 1.10.0, the same clean-main check also reports layout changes in src/MLP.jl and test/shared/DeepBSDE_Han.jl.

Passing after

$ julia +release --project=../.tmp/runic-env -m Runic --check --diff .
# exit 0; no output

NNKolmogorov also ran in the Core group, and the complete group exited successfully; its summary was not retained in the captured terminal tail.

Not verified here

• The GPU path was not run because a functional CUDA device is unavailable. The changed GPU-gated line is formatting-only.
• Docs were not rebuilt on this formatter-only branch because current main has a separately bisected docs self-compatibility failure. Draft PR Fix docs compatibility with HighDimPDE 2 #170 fixes that one-line docs compatibility issue and passes the strict docs build.
• Julia pre-release and downstream jobs were not run locally.

Final hosted validation is green.

• 17 required checks passed.
• The matrix includes Core on Julia 1/LTS/pre across Ubuntu, macOS, and Windows; QA; the LTS GPU group; the standalone GPU test; downgrade; Runic; Runic suggestions; spelling; and test detection.
• The documentation job was skipped as expected for this formatting-only change.
• After git fetch upstream, git rev-list --count HEAD..upstream/main returned 0; the branch is current with upstream main.
