- Fix go.mod version format from '1.23.2' to '1.24' to align with vultisig-go
- Add toolchain specification for Go 1.23.2 compatibility
- Successfully compile vultitool binary with working CLI interface
- Add 'vultitool' binary to .gitignore to exclude build artifacts
- Remove tracked binary from git index while preserving local executable

The build now works properly and follows standard practices for Go projects
by excluding compiled binaries from version control.

Resolves module parsing errors and establishes clean build environment.
