Jake WriterandClaude Opus 5.5 86a20c73b7 fix(python): repair devicePixelRatio the same way on every launch ...

The DPR repair snaps an off-grid ratio to the nearest real scaling step and
keeps the first of two equally near steps. The steps were frozenset
literals, and a frozenset literal iterates in one order when the module is
compiled from source and another when it is loaded back from a .pyc. So a
midpoint such as 1.125 became 1.25 on the first launch after an install and
1 on every launch after it: the same pinned identity presented two different
devicePixelRatio values.

The steps are now ascending tuples, so a tie always goes to the lower step.
The test runs the repair in two fresh interpreters that share a bytecode
cache, compiling in the first and loading in the second. It failed before
this change.
