122 char literal paren in args

// PIN (found by AoC day 1): a char literal containing a paren — '(' or ')' —
// inside invocation args must not confuse the arg scanner. The paren-depth
// scan was quote-blind: '(' inflated the depth, the closing paren was never
// found, and the args were SILENTLY DROPPED (empty args, no error), so
// `if(c == '(')` lost its condition and downstream KORU100 blamed the binding.
