Fix Downgrade CI: raise PrecompileTools compat floor to 1.1

[ChrisRackauckas-Claude]

Please ignore until reviewed by @ChrisRackauckas.

Problem

The Downgrade / Downgrade Tests - Core lane on master is red. The error:

ERROR: LoadError: UndefVarError: `@recompile_invalidations` not defined
in expression starting at .../StaticArrayInterface/qmd3i/src/StaticArrayInterface.jl:19
Failed to precompile StaticArrayInterface ...
Failed to precompile EllipsisNotationStaticArrayInterfaceExt ...
Core/static_array_interface.jl | Error 1 / Total 1

Root cause

The downgrade run pins direct deps to their [compat] floor. EllipsisNotation had PrecompileTools = "1.0.1". With PrecompileTools pinned at 1.0.1, the resolver pairs it with StaticArrayInterface v1.10.0 (every registry version of StaticArrayInterface, 1.4.1 through 1.10.0, declares PrecompileTools = "1", so the latest is chosen).

Every one of those StaticArrayInterface versions does:

using PrecompileTools
@recompile_invalidations begin
    ...
end

but @recompile_invalidations was only added to PrecompileTools in 1.1.0. So under the downgrade resolution StaticArrayInterface fails to precompile with UndefVarError: @recompile_invalidations not defined, which cascades into EllipsisNotationStaticArrayInterfaceExt and the static_array_interface.jl Core test.

StaticArrayInterface advertising PrecompileTools = "1" is itself too loose (upstream bug), but EllipsisNotation can avoid the bad pairing by requiring PrecompileTools >= 1.1, where the macro exists.

Fix

Raise PrecompileTools compat floor 1.0.1 -> 1.1, and bump the package version 1.10.0 -> 1.10.1 (compat change requires a release for registration).

Verification (local, Julia LTS 1.10.11)

Reproduced the exact failure before the fix (PrecompileTools pinned 1.0.1):

✗ Static
✗ StaticArrayInterface
✗ EllipsisNotation → EllipsisNotationStaticArrayInterfaceExt
UndefVarError: `@recompile_invalidations` not defined

After the fix (PrecompileTools pinned at the new floor 1.1.0, StaticArrayInterface v1.10.0 resolved):

✓ EllipsisNotation
✓ StaticArrayInterface
✓ EllipsisNotation → EllipsisNotationStaticArrayInterfaceExt

All Core test files pass:

======== RUN basic.jl ========          (passes)
CartesianIndex          | 6  / 6
StaticArrayInterface    | 10 / 10
Allocation Tests        | 4  / 4
