- Remove dead code: empty string case in errorsToStderr switch (unreachable due to early return)
- Add test for bare -r flag without argument to verify it defaults to 0

Feb 5, 2026

ODBC sqlcmd allows -r without an explicit value, defaulting to 0
(enable stderr redirection for severity >= 11). Previously go-sqlcmd
required -r0 or -r1 explicitly.

Changes:
- normalizeFlags: Accept empty value for -r flag
- getOptionalIntArgument: Return 0 for empty value instead of -1
- Add tests for bare -r flag
