MAX changelog updates:

- `max benchmark` renames `--warmup-to-steady-state` to `--warmup-multiturn`,  
since it applies only to multi-turn workloads and is unrelated to the  
steady-state measurement window. The old flag, its workload and config  
file keys, and `MODULAR_WARMUP_TO_STEADY_STATE` still work and log a  
deprecation warning. Result files record the option as `warmup_multiturn`  
under `client_args`.

- Built-in custom ops are now named after their class instead of `mo.`,  
which is kept for the graph compiler’s own ops. For example,  
`mo.launch_host_func` and `mo.inplace_memcpy` are now  
`runtime.launch_host_func` and `runtime.inplace_memcpy`, and  
`mo.matmul_swiglu` is now `matmul.swiglu`. Update the name passed to  
`ops.custom()` in graphs that call these ops directly.

- The legacy `Layout` and `IntTuple` types have been removed from the `layout`  
package, along with the `layout.layout` and `layout.int_tuple` modules, the  
`to_layout()`, `LTToTTLayout` and `print_layout()` bridges, and the legacy  
`tile_layout_k_major()`, `tile_layout_mn_major()` and  
`tile_sf_layout_k_major()` constructors. Use the typed layouts in  
`layout.tile_layout` (`Layout`, also exported as `MixedLayout`) for layout  
values, `Coord` for shapes, strides and indices, and the `*_typed` tile  
layout constructors in `layout.tensor_core_async`. `wgmma_desc_sbo_lbo()`  
and `wgmma_canonical_strides()` replace `tile_to_descriptor()`, and `print()`  
accepts a typed layout directly.

- The `load_fn`, `compute_fn` and `compute_finalize_fn` callbacks of  
`stencil()` and `stencil_gpu()` in `max.algorithm` now take a `Coord`  
instead of an `IndexList[rank]`. `map_fn` still takes and returns  
`IndexList`. The coordinate holds the same values as before:

Mojo changelog updates:

- [mojo-lang] add `elaboration-stats` to CompileTimeProfiling.md
- [stdlib] Add a filter iterator
- [External] [stdlib] Make ord raise on invalid runtime input (#108755)
