Hat support for mojo 1.0

Community Showcase
1

hat is a cargo-like wrapper around pixi, and is now updated for precompile / .mojoc changes.

Example:

# Create a new binary project
hat new --name mojo-grep

# Create a new lib project
hat new --lib --name amazing-lib

# Track the latest nightly compiler instead of stable Mojo 1.0.0
hat new --nightly --name nightly-project

# Build project (defaults to release build)
hat build 

# Build with debug and asserts on
hat build --debug

# Test your project
hat test

Extramojo and mojopt have also been updated to 1.0, but those are a bit less exciting:

There is also a pixi PR for the pixi-build-mojo backend to use precompile/mojoc: fix(pixi-build-mojo): use .mojoc with precompile by sstadick · Pull Request #6860 · prefix-dev/pixi · GitHub that will remove warnings when using hat.
