   After reviewing the repeated recovery fixes as a whole, I simplified the PR 
in 87610602065. It no longer adds a parse_sql-specific batch grammar or 
malformed-BEGIN recovery policy. parse_sql now reuses the existing positioned 
SqlStatementSplitter path and stock-parses each emitted segment, as in the 
original design. Valid compound scripts, variable-reference validation, 
extension fallback, and malformed-input behavior are therefore inherited from 
the shared splitter. The UTF-16 offset mapping, SQL-whitespace trimming, 
source-span contract, and closed-comment clarification remain. Focused 
splitter/result/expression/golden tests and both SQL scalastyle targets pass. 
Any stronger malformed-compound recovery should be addressed separately in the 
shared splitter so all callers have one contract.
