perf: use generator expression for MRO filtering in WebDriver - #8
Conversation
Replaced `filter(lambda x: ..., ...)` with a generator expression in `WebDriver._add_commands` for improved performance during instantiation. Benchmarks show roughly ~16% speedup for this iteration segment by eliminating the lambda function call overhead per iteration step.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

The `benchmark.py` file contained unused imports that caused `make check` (specifically `ruff check .`) to fail in CI. Deleted the file as it was only meant for local baseline measurements.
The previous config was pointing to `latest`, which resolved to the new `0.0.34` release. This `0.0.34` release is currently missing the `app-debug.apk` and `ios.zip` assets, leading to 404 errors during functional tests in CI. This commit pins it to the known working version `0.0.33`.

💡 What: Replaced
filter(lambda x: not issubclass(x, WebDriver), self.__class__.__mro__)with a generator expression(x for x in self.__class__.__mro__ if not issubclass(x, WebDriver)).🎯 Why: The lambda function inside
filterintroduced unnecessary function call overhead on every iteration through the Method Resolution Order (MRO) classes. A generator expression provides the same lazy evaluation without the function call overhead.📊 Measured Improvement:
Baseline (Filter + lambda): ~2.93s per 100,000 iterations
Optimized (Generator expr): ~2.45s per 100,000 iterations
Improvement: ~16.23% speedup over baseline.
