MAX changelog updates:

- Rewrote the eager-interpreter `mo.mutable.store.slice` handler to write  
slices via a device-side Mojo kernel instead of a host numpy round-trip.  
GPU buffers no longer full-buffer D→H→D on every call, and `bfloat16`  
and `float8_*` dtypes are now supported. `float4_e2m1fn` remains  
unsupported.

Mojo changelog updates:

- [mojo-stdlib] Finish migrating Variadic+Type|ParameterList
- [MojoLang] Use `NoneType` for literal constructor marker
- [mojo-lang] Allow t-strings in comptime assert messages
