Skip joining for a single string, skip normalization when none is configured, and copy the name list once instead of four times.
getPath+resolve: ~790 -> ~460 ns/op, 2.5 KB -> 1.25 KB/op (JDK 21, benchmark from #97).Checked with Endive (wasi-tests, machine-tests, wabt, Zig stdlib suite): no regressions.
