test: multi-crate release v4.7.6

[galargh]

This is a test PR to verify the workspace-aware release automation.

It bumps the workspace version to 4.7.6, which affects multiple interdependent crates (fvm, fvm_shared, fvm_sdk, fvm_integration_tests).

The goal is to verify that release-check correctly runs cargo publish --workspace --dry-run and succeeds.
