feat(packages): add graphify v0.7.10

Add graphify, a tool that turns any folder of code, docs, papers, images,
or videos into a queryable knowledge graph for AI coding assistants.

Includes tree-sitter grammar filtering to use only grammars available in
nixpkgs, with missing grammars falling back to runtime downloads.
