Marco Allegretti f535020600 feat: karapace-core — engine orchestration, lifecycle state machine, drift control ... - Engine: init → resolve → lock → build → enter/exec → freeze → archive → destroy - Cached store_root_str avoiding repeated to_string_lossy() allocations - WAL-protected build, enter, exec, destroy, commit, restore, GC operations - Overlay drift detection: diff/commit/export via upper_dir scanning - Deterministic snapshot commit with composite identity hashing - Atomic restore via staging directory swap - StoreLock: compile-time enforcement via type parameter on gc() - Signal handler: SIGINT/SIGTERM graceful shutdown with AtomicBool - Push/pull delegation to karapace-remote backend - Crash recovery: stale .running marker cleanup on Engine::new() - Integration tests, E2E tests, crash injection tests, ENOSPC simulation - Criterion benchmarks: build, rebuild, commit, restore, GC, verify		2026-02-22 18:37:02 +01:00
