Should this have a small migration guide entry to state that an additional feature is required when using |

its a default feature, so unless you're using default-features=false there's no migration |

# Objective - add support for alternate zstd backend through `zstd` for faster decompression ## Solution - make existing `zstd` feature only specify that support is required, disambiguate which backend to use via two other features `zstd_native` and `zstd_rust`. - Similar to the approach taken by #18411, but we keep current behavior by defaulting to the rust implementation because its safer, and isolate this change. NOTE: the default feature-set may seem to not currently require `zstd`, but it does, it is enabled transitively by the `tonemapping_luts` feature, which is a default feature. Thus this does not add default features. ## Testing - Cargo clippy on both feature combinations

# Objective Fixes #21089 The migration guide for the `zstd` feature changes didn't explain how to migrate from the old `zstd` feature to the new split features. ## Solution Added migration instructions showing that the old `zstd` feature should be replaced with either `zstd_rust` (safe default) or `zstd_c` (faster but unsafe). ## Testing - Documentation change only, no code to test - Verified the feature change in git history (PR #19793) ## Link to the issue: [https://github.com/bevyengine/bevy/issues/21089](https://github.com/bevyengine/bevy/issues/21089) --------- Co-authored-by: Alice Cecile <[email protected]>
