test: bump StochasticDiffEq compat floor to 7.1 (fix Downgrade lane)#469

Conversation
The Downgrade lane min-resolves the test env to StochasticDiffEq 7.0.0,
whose compat allows DiffEqNoiseProcess >= 5.13.0. DiffEqNoiseProcess < 5.30.0
only supports DiffEqBase 6, while StochasticDiffEq 7.0.0 itself requires
DiffEqBase 7, so the floor graph is unsatisfiable ("no versions left" for
DiffEqBase).
StochasticDiffEq 7.1.0 raises its DiffEqNoiseProcess floor to 5.30.0 (the
first DiffEqNoiseProcess release compatible with DiffEqBase 7). Flooring the
test compat at 7.1 makes the downgrade floor graph resolve cleanly.

Summary
Bumps the
StochasticDiffEqtest compat floor from"7"to"7.1"intest/Project.tomlto fix the failing Downgrade CI lane.Root cause
The Downgrade lane min-resolves the test environment. With the floor at
"7", the resolver selectsStochasticDiffEq 7.0.0, whose compat allowsDiffEqNoiseProcess = 5.13.0 - 5. The min-resolver then drivesDiffEqNoiseProcessdown to5.13.0. But:DiffEqNoiseProcess < 5.30.0only supportsDiffEqBase 6(DiffEqBase = 6.11.0 - 6/6.61.0 - 6).StochasticDiffEq 7.0.0itself requiresDiffEqBase = 7.These are mutually exclusive, so the floor graph is unsatisfiable — the resolver reports
Unsatisfiable requirements detected for package DiffEqBase [2b5f629d] ... no versions left.StochasticDiffEq 7.1.0raises its own floor toDiffEqNoiseProcess = 5.30.0 - 5, andDiffEqNoiseProcess 5.30.0is the first release whose compat isDiffEqBase = 6.61.0 - 7(i.e. the first to support DiffEqBase 7). Flooring the test compat at7.1makes the whole floor graph resolve cleanly.Validation (local, Julia 1.10 / lts)
Reproduced the exact CI failure and confirmed the fix with Pkg's resolver:
StochasticDiffEq 7.0.0+DiffEqNoiseProcess 5.13.0(its floor) +DiffEqBase 7→Unsatisfiable requirements detected for package DiffEqBase ... no versions left.StochasticDiffEq 7.1.0+DiffEqNoiseProcess 5.30.0(its floor) +DiffEqBase 7→ resolves cleanly; manifest pinsStochasticDiffEq 7.1.0,DiffEqNoiseProcess 5.30.0,DiffEqBase 7.0.0.Registry compat facts confirmed directly:
StochasticDiffEq7.0→DiffEqNoiseProcess = 5.13.0 - 5;7.1 - 7→DiffEqNoiseProcess = 5.30.0 - 5.DiffEqNoiseProcess5.25 - 5.29→DiffEqBase = 6.61.0 - 6;5.30 - 5→DiffEqBase = 6.61.0 - 7.Compat-only change, no source touched, no public API impact.
