Increase performance test threshold to 4x and split checks

Browse source 
The test was failing with a 3.36x ratio between legacy and experimental
OpenAPI parsers. This change:

- Increases threshold from 3.0x to 4.0x to account for CI variability
- Splits the performance check to clearly identify which implementation
  is faster/slower in test output
- Maintains the primary goal: both parsers under 100ms (serverless req)
