## Message

```
std/lib: {fs,io,posix} test clean up

* use `tmp.dir.realpathAlloc()` to get full path into tmpDir instances
* use `testing.allocator` where that simplifies things (vs. manual ArenaAllocator for 1 or 2 allocs)
* Trust `TmpDir.cleanup()` to clean up contained files and sub-trees
* Remove some unnecessary absolute paths (enabling WASI to run the tests)
* Drop some no-longer necessary `[_][]const u8` casts
* Add scopes to reduce `var` usage in favor of `const`

```
