feat: Phase 4A CP1 — epoch, lease, role state machine, write gate
...
Local fencing primitives for block volumes. Every write path validates
role + epoch + lease before accepting data. RoleNone (default) skips
all checks for Phase 3 backward compatibility.
New files: epoch.go, lease.go, role.go, write_gate.go
Modified: superblock.go (Epoch field), blockvol.go (fencing fields,
writeGate in WriteLBA/Trim), group_commit.go (PostSyncCheck/Gotcha A),
dirty_map.go (P3-BUG-9 power-of-2 panic)
Bug fixes: BUG-4A-1 (atomic epoch), BUG-4A-2 (CAS SetRole),
BUG-4A-3 (mutex SetEpoch), BUG-4A-4 (single role.Load),
BUG-4A-6 (safeCallback recover)
837 tests (557 engine + 280 iSCSI), all passing.
