MAX changelog updates:

- Removed jump forward decoding (`compute_ff_tokens`) from structured output.  
The bitmask constraint alone ensures valid structured output, matching the  
approach used by vLLM and SGLang.
- Fixed integer indexing into a graph tensor (e.g. `x[0]` on a `(2, 3)`  
tensor) failing graph compilation with  
`mo.static.reshape op input and output elements do not match`. A  
reshape-through-slice optimization pattern was incorrectly rewriting  
the slice + squeeze pattern produced by integer indexing, generating a  
reshape whose element count did not match the input.  
([Issue #6440](https://github.com/modular/modular/issues/6440))
