      Category toggles used to enable/disable specs by name.

      Keys map directly to specs (e.g., `python` controls `specs.python`).
      Set a category to `false` to skip its dependency/plugin specs.

      Available categories:
      - clickhouse: Clickhouse client and tools
      - customPlugins: local plugin specs
      - external: external tools and integrations
      - general: core Neovim plugins/features
      - gitPlugins: git-related plugins
      - julia: Julia tooling and packages
      - lua: Lua tooling and LSPs
      - markdown: markdown tooling and plugins
      - nix: Nix tooling and plugins
      - optional: optional tools and utilities
      - python: Python tooling and plugins
      - r: R tooling and plugins
      - test: test-only tooling (disabled by default)
      - treesitterParsers: Treesitter parsers
      - utils: general utilities
