feat: add V2 protocol simulator and enginev2 sender/session prototype
Adds sw-block/ directory with:
- distsim: protocol correctness simulator (96 tests)
- cluster model with epoch fencing, barrier semantics, commit modes
- endpoint identity, control-plane flow, candidate eligibility
- timeout events, timer races, same-tick ordering
- session ownership tracking with ID-based stale fencing
- enginev2: standalone V2 sender/session implementation (63 tests)
- per-replica Sender with identity-preserving reconciliation
- RecoverySession with FSM phase transitions and session ID
- execution APIs: BeginConnect, RecordHandshake, BeginCatchUp,
RecordCatchUpProgress, CompleteSessionByID — all sender-authority-gated
- recovery outcome branching: zero-gap, catch-up, needs-rebuild
- assignment-intent orchestration with epoch fencing
- design docs: acceptance criteria, open questions, first-slice spec,
protocol development process
