0.14.3 makes import-git spend far less CPU on large histories: each artifact is delta-encoded against its likely source first, as Fossil's import does, and neighbouring artifacts are tried only when that delta is not small enough. On a 37,000-commit history user CPU fell by 42% and the store grew by 0.13%. The import's progress total now counts the pull-request heads it imports, so it no longer runs past 100%, and submanifest show reads the saved log index instead of the whole store. Stores, caches and the wire are unchanged. Built with Zig 0.17.0.
