Pull request overview

This PR adds automated publishing of the VmgsTool utility as GitHub releases when the crate version changes. The implementation includes flowey pipeline infrastructure to extract version information from the Cargo.toml file, build VmgsTool for multiple targets (x86_64 and aarch64, for both Windows and Linux), and publish them as GitHub releases.

Changes:

• Added version field "0.1.0" to vmgstool Cargo.toml
• Refactored VmgstoolOutput structure to include version information alongside binaries
• Added new publish_gh_release infrastructure in flowey_lib_common for creating GitHub releases
• Integrated vmgstool publishing into CI pipeline (only runs on CI, not PR builds)
