> UStore for Mojo

Let Pixi build the package from source, with no channel to add and no linker flag to pass; the engine arrives as its run dependency, in the environment prefix `mojo build` bakes as runpath.

```toml
[workspace]
preview = ["pixi-build"]

[dependencies]
ustore_mojo = { git = "https://github.com/unum-cloud/UStore", subdirectory = "mojo", tag = "v1.0.0-rc.1" }
```

From a checkout, `pixi run test` builds the engine through the tree's own CMake and runs `mojo/test.mojo` against in-memory databases.
On Linux the engine builds against conda-forge's glibc 2.39 sysroot, whose kernel headers carry the `io_uring` flags the NVMe engine needs.
