gnomancer v0.5.0

• Family mode: gnomancer family dad.zip mom.zip me.zip (and the MCP tool family). Shared DNA segments per pair via apriha/lineage with a relationship estimate, shared maternal/paternal lines, side-by-side panel genotypes, which parent each allele came from for parent-parent-child sets, and a Mendelian-consistency check. Synthetic family generator for testing.
• Haplogroup guide pages on gnomancer.com, linked from the report's lineage cards
• Installer skips Pythons whose XML module is broken (Homebrew bottles on macOS 26.2) and can fall back to a uv-managed Python
