Expose context flag defined in terms of "# of enclosing tree-sitter AST nodes"?

[helixbass]

It strikes me that (vs --after-context/--before-context) we could provide a "smarter" context where you could declaratively say eg "show me one level of AST parent above matching nodes as context"?

Thinking about this a little bit, it does sound like an intuitive/possibly useful feature

But I think the implementation would be pretty non-trivial, it looks like it would involve "wiring up" a tree_sitter::Node-aware idea of "context" through at least the searcher
