0.10.1 fixes two horizon-clone defects the nightly soak found: a crash while a store's header was restamped could leave a store every command refused, though its data was intact, and a deepen from a zit server could stop short when a sub-manifest arrived as a delta. zit daemon also records merges and answers merge_base and diff. Stores, caches and the wire are unchanged from 0.10.0. Built with Zig 0.17.0.
