Rob23oba b7f433c5b9 fix: behavior of String.prev (#9441) ... This PR fixes the behavior of `String.prev`, aligning the runtime implementation with the reference implementation. In particular, the following statements hold now: - `(s.prev p).byteIdx` is at least `p.byteIdx - 4` and at most `p.byteIdx - 1` - `s.prev 0 = 0` - `s.prev` is monotone Closes #9439		2025-07-21 10:50:14 +00:00
