issue: #41570
Fix issue where growing and sealed segments could be searched
simultaneously, causing inflated count(*) results. This was caused by
logic introduced in PR #42009 that made sealed segments readable before
target version advancement.
Changes include:
- Fix conditional filtering logic in PinReadableSegments to prevent
sealed segments from becoming readable prematurely
- Use target version filter for full results (ratio=1.0) to ensure
sealed segments only become readable after target advancement
- Use query view segment list filter for partial results (ratio<1.0) to
maintain backward compatibility
- Simplify target version setting in AddDistributions to prevent
premature segment readability
- Add logging for redundant growing segments during sync
- Add comprehensive unit tests covering the duplicate segment scenario
This fix ensures count(*) queries return accurate results by preventing
the same segment from being counted in both growing and sealed states.
