fix: broken SQL in update manifests — line-by-line instead of complete statements

build-update.ps1 was reading SQL migrations line-by-line, causing
multi-line CREATE TABLE/INSERT statements to be stored as fragments
in manifests. Fixed to strip comments, join lines, and split by
semicolons. Fixed ver_0.324_manifest.json with correct SQL statements.
Added try-catch in UpdateRepository to prevent fatal crashes on SQL errors.
