I think fat_root was already a helper doing this?

it uses entrypoint rather than module_root

There's fat_root and fat_entrypoint, the former uses module_root (maybe it could be renamed)

What happens if we try to execute a package with multiple hugrs, where the function only exists in one of them?
It looks like run_function panics if given a multi-hugr package, but here it looks like it'd be supported. Should we check and error-out early instead?

🤖 I have created a release *beep* *boop* --- ## [0.21.0](guppylang-v0.20.0...guppylang-v0.21.0) (2025-08-04) ### ⚠ BREAKING CHANGES * All compiler-internal and non-userfacing functionality is moved into a new `guppylang_internals` package * `guppy.compile(foo)` and `guppy.check(foo)` replaced with `foo.check()` and `foo.compile()` * default HUGR output uses compressed binary encoding. * `guppylang.tracing.object.GuppyDefinition` moved to `guppylang.defs.GuppyDefinition` `guppylang.tracing.object.TypeVarGuppyDefinition` moved and renamed to `guppylang.defs.GuppyTypeVarDefinition` * All `to_hugr` methods on types, arguments, and parameters now require a `ToHugrContext` `CompileableDef.compile_outer` now requires a `ToHugrContext` `guppy.hugr_op` now passes the compiler context to the function generating the op `CheckedFunctionDef` now implements `MonomorphizableDef` instead of `CompileableDef` `CompilerContext.build_compiled_def` now requires an instantiation for the definition's type parameters The `ToHugrContext` protocol now requires two additional methods: `type_var_to_hugr` and `const_var_to_hugr` `CompilerContext.{compiled, worklist}` and `CompilationEngine.compiled` are now indexed by a tuple of `DefId` and optional `PartiallyMonomorphizedArgs` * comptime code that previously used constant integers outside i64 will now fail to compile. * Capturing closures are now disabled by default. Enabling them requires calling `guppylang.enable_experimental_features()`, however note that they are not supported throughout the stack. ### Features * Add `Future` type ([#1075](#1075)) ([5ad7673](5ad7673)) * add error when constant integer out of bounds ([#1084](#1084)) ([eee77ae](eee77ae)) * Add guppy version metadata to hugr entrypoint ([#1039](#1039)) ([0eafbd9](0eafbd9)), closes [#1037](#1037) * Add manual registration of extensions ([#1045](#1045)) ([4b42936](4b42936)) * add qsystem op for measure leaked ([#1057](#1057)) ([c555727](c555727)) * add selene via optional feature and use for testing ([#1081](#1081)) ([cefc70e](cefc70e)) * Add support for V and Vdg.
