Eliminate ~400 lines of duplicated test boilerplate across 7 integration test files by introducing a shared `common/mod.rs` module with: - `WarmRuntime`: shared image cache at /tmp/boxlite-test/ for VM tests - `IsolatedRuntime`: per-test TempDir for non-VM tests (parallel-safe) - `alpine_opts()` / `alpine_opts_auto()`: replaces ~55 inline BoxOptions Nextest config updated with granular binary-level test groups: - Non-VM tests (runtime, shutdown, network) → parallel (max-threads=4) - VM tests → serial (max-threads=1) - CLI completion tests → parallel (max-threads=num-cpus) Makefile gains `test:warm-cache` target to pre-pull alpine:latest, wired as a dependency of `test:integration`. Execution_shutdown.rs sleeps reduced from 500ms to 50ms (saves ~3.6s).
- WarmRuntime → ParallelRuntime with per-test TempDir and symlinked image cache, enabling concurrent VM test execution - Simplify nextest config from 6 test groups to 1 (serial-cli only) - Add cargo-nextest + cargo-llvm-cov coverage with Codecov upload to CI - Add proptest property-based tests for BoxID and layout paths - Add boot timing instrumentation (shim, krun context, guest agent) - Add timing_profile.rs diagnostic test and boot latency analysis doc
