Previously, the logic in peekDelimiterInclusive (when the delimiter was not found in the existing buffer) used the `n` returned from `r.vtable.stream` as the length of the slice to check, but it's valid for `vtable.stream` implementations to return 0 if they wrote to the buffer instead of `w`. In that scenario, the `indexOfScalarPos` would be given a 0-length slice so it would never be able to find the delimiter. This commit changes the logic to assume that `r.vtable.stream` can both: - return 0, and - modify seek/end (i.e. it's also valid for a `vtable.stream` implementation to rebase) Also introduces `std.testing.ReaderIndirect` which helps in being able to test against Reader implementations that return 0 from `stream`/`readVec` Fixes #25428
