feat: add comprehensive test suite, CI/CD pipeline, and VM CLI commands

- 211 new tests across all 9 crates (173 → 384 total, zero failures)
- CI/CD pipeline with cross-platform matrix (Linux, macOS, Windows)
- cargo-deny dependency audit (licenses, advisories, bans, sources)
- ctst vm start/stop CLI commands for manual VM management
- Engine vm_start() and vm_stop() methods with VMBackend downcasting
- Core tests for namespaces, cgroups, filesystem, capability (23 root-gated)
- CLI tests for all 10 subcommands + docker-compose converter
- Runtime backend tests (Linux + VM)
- SDK tests (ContainerBuilder, GraphResolver, EventListener)
- TUI tests (app state, event handling, UI widgets)
- eBPF tests (tracer, file/network monitors, programs)
- tempfile dev-dependency added to containust-sdk
