URL: https://github.com/apache/hudi/pull/17863
### Describe the issue this Pull Request addresses
Adds validation to detect and reject invalid write stats with zero operation
counts, preventing inconsistent metadata from being committed.
### Summary and Changelog
- Added `validateWriteStats()` method to validate write stats before
finalizing writes
- Validates that at least one of `numWrites` or `numDeletes` is non-zero
- Throws `HoodieInconsistentMetadataException` when both counts are zero
- Added comprehensive test coverage for validation scenarios
### Impact
- Adds fail-fast validation for inconsistent write stats
- No breaking changes - only rejects invalid operations that shouldn't
succeed anyway
- Improves error messages for easier debugging
### Risk Level
**Low**
New validation catches edge cases that would have caused issues downstream.
No impact on valid operations.
### Documentation Update
Added Javadoc explaining the validation. No other documentation changes
needed.
