feat(json,yaml): add tree-sitter modes, formatting, and jq integration

New prog-json module: json-ts-mode with jq formatting (C-; f) and
jq-interactively (C-c C-q). Upgraded prog-yaml to yaml-ts-mode with
prettier formatting. Both use treesit-auto for grammar management.
Includes 18 new tests (10 JSON, 8 YAML), 185/185 passing.
