//! doover-core — snapshot, journal, and undo primitives for AI agent shell actions.
//!
//! Module map (built strictly test-first; see doover-implementation-plan.md):
//! - `registry` (step 1): reversibility classification of commands
//! - `parser` (step 2): bash parsing + affected-path scope resolution
//! - `snapshot` (step 3): content-addressed CoW snapshot store
//! - `journal` (step 4): SQLite action journal
//! - `hooks` (step 5): harness adapters (Claude Code first)
//! - `undo` (step 6): restore engine with conflict detection
