The PR description states "Enhance BinlogSplitReader to auto-capture newly added tables matching the pattern", and the comment here claims "BinlogSplitReader will handle the auto-capture", but there are no changes to BinlogSplitReader.java in this PR. The existing logic in BinlogSplitReader.hasEnterPureBinlogPhase() (line 318-323) only checks isScanNewlyAddedTableEnabled(), not isScanBinlogNewlyAddedTableEnabled(). This means the feature will not actually work as described. BinlogSplitReader needs to be enhanced to check isScanBinlogNewlyAddedTableEnabled() and handle newly added tables accordingly.

The PR description mentions that validation logic should ensure binlog-only mode works only with stream-only startup modes (latest, earliest, specific offset, timestamp). However, this validation is missing. When scanBinlogNewlyAddedTableEnabled is true but the startup mode is not stream-only (e.g., initial or snapshot), the behavior may be incorrect. Add validation to check if startupOptions.isStreamOnly() when scanBinlogNewlyAddedTableEnabled is enabled.

throw new IllegalArgumentException(
"'scan.binlog.newly-added-table.enabled' can only be enabled when using a "
+ "stream-only startup mode (latest-offset, earliest-offset, specific-offset, or timestamp).");
