Possibly related issues

• ChainSafe/forest 7546: The NV29 tracking issue lists updating Forest to use the new ref-fvm dependencies as preparation. This PR updates FVM dependency constraints, but its connection to NV29 is not confirmed.

Possibly related PRs

• ChainSafe/forest#7850: It updates the fvm_shared4 version constraint in the same file, and its changes may depend on the version selected here.

Merge Risk: Moderate · up to 22ce9

The FVM bump cannot be resolved from the registry until compatible actors-utils releases are published, and the lockfile currently references an unpublished fvm_actor_utils version. Hold the merge until upstream releases the fix, then update the dependency and regenerate Cargo.lock.

Explanation

The title "chore: bump FVMs" matches the main change. The raw summary shows the fvm 2, 3, and 4 runtime dependencies and their fvm_shared counterparts, plus the fvm_shared3 and fvm_shared4 dev dependencies, moved to newer versions in Cargo.toml. The PR objectives confirm the goal is to bump FVM to the newest version. The title is short, specific, and uses the standard conventional-commit prefix. It does not name the exact versions, which is acceptable because the title does not need to cover every detail.
