snomiao 9d4f484a60 [feat] optimize Playwright test sharding for balanced execution times ...

- Implement weighted test distribution algorithm to balance shard execution times
- Create automated shard optimization script that analyzes test complexity
- Remove unnecessary sharding for fast test suites (mobile-chrome, chromium-0.5x, chromium-2x)
- Update GitHub workflow to use optimized shard configuration
- Add comprehensive sharding documentation

The previous naive sharding caused shard 5 to take 9 minutes while others completed in 2-6 minutes.
This was due to interaction.spec.ts containing 61 tests with 81 screenshot comparisons.

New approach uses weighted distribution based on:
- Number of tests per file
- Screenshot comparison count
- Test complexity and historical execution time

Results:
- Achieved ~4.5% imbalance (vs previous ~80%)
- All chromium shards now complete in 3-4 minutes
- Total CI time reduced from 9 minutes to ~4 minutes
