[#36] test(e2e): flag transposed orientation as a known flake and bail on first failure

[yuji-hatakeyama]

assertDimensions now detects the transposed case and fails with an explicit "known flake — re-run" message instead of a bare expect(1536).toBe(1024). --bail stops the run on the first failure, so the multi-minute Test C (which depends on A/B output) doesn't run needlessly.

Closes #36
