release: patch syntax, compiler, db, csr

Six fixes, all found by driving a real application rather than by the suite:

- syntax: a quote or brace inside a regex literal unbalanced the brace scanner
- syntax: block comments between members failed to parse, while the same
  comment inside a braced body was fine
- compiler: pages never emitted `data-wrn-loop-locals`, so a loop variable in
  a handler threw ReferenceError at click time with a green build
- csr: client-rendered `data-for` items never carried the marker either, so a
  component's output binding silently dropped every call while a plain DOM
  handler in the same position worked
- db: the query generator baked the checkout's line endings into generated
  SQL literals, so every build dirtied the working tree
