Optimize CI/CD and improve versioning system

- Created `internal/pkg/version` to handle version metadata.
- Added `version` command to CLI in `cmd/cims/main.go`.
- Updated `Makefile` to inject version info via `-ldflags`.
- Updated `.github/workflows/ci.yml` to trigger on all pushes and include a cross-platform build job.
- Updated `.github/workflows/release.yml` to inject version info into release binaries.
- Bumped Go version to 1.24 in CI to match `go.mod`.
