Port a pre-1.0 winnow parser to winnow 1.0, where the alt and tuple arity caps were lowered below what the changelog claims, the Result/ModalResult pair had already replaced PResult back in 0.7.0, dec_uint silently refuses leading zeros on every version, and 0.7.14 added a built-in Pratt parser

컨트랙트

• assert the pre-1.0 spellings that did NOT change still hold: literal for tag, take for recognize, the count range first in repeat and separated, the stream advanced through &mut, parse_peek returning (remaining, output), and parse reporting the offset where it stopped
• assert alt accepts at most 9 branches on 1.0 so a 12-keyword lexer must nest or pass an array, and both spellings agree on every keyword
• assert alt takes the first matching branch rather than the longest, so reordering the same two branches changes which one wins
• assert a tuple used as a sequence holds at most 11 parsers, so an 11-parser timestamp works and a 13-parser one needs seq! with ignored _ fields
• assert dec_uint stops at a leading zero, yielding 0 and leaving the remaining digits, while digit1 with parse_to accepts zero padding
• assert winnow::Result and ModalResult parse identically and glob-importing the crate shadows core Result, but only ErrMode implements ModalError, so cut_err needs the modal form and stops alt falling through to a catch-all
• assert the built-in expression Pratt parser honours binding power, left and right associativity, and an operator that returns an error
