Modernize APIs and speed up slice codecs (#24)

* Apply gopls modernize fixes

Replace interface{} with any, use range-over-int and reflect.TypeFor,
and drop the obsolete +build line now that the module requires Go 1.25.

* Fix reflect.SliceHeader vet warnings

Replace deprecated SliceHeader/StringHeader casting with unsafe.Slice
and unsafe.StringData so go vet stays clean on Go 1.25.

* Restore zero-copy nocopy integer slice decode

rv.Set(reflect.NewAt(...)) allocated on decode and regressed
nocopy/u64-dec. Mutate the slice header in place again without
using deprecated reflect.SliceHeader.

* Speed up slice decode and sorted varint codecs

Reuse slice capacity on decode, batch varint writes into bytes.Buffer,
and decode sorted integer slices without reflect.Append so hot paths
allocate less and run faster.

* Drop benchmark reference comparisons

Remove vs-ref (JSON and safe baselines) so benches only report absolute
timing and vs-prev deltas.
