`find` "tool"

[DavidSouther]

#18 describes an edit mode using lines. But which lines? Most authors can read line numbers in their editor, but that's a PITA.

Add a find "tool" (not an LLM tool as in requested by the LLM itself, but maybe it could be in the future) that "finds" a section of the input document based on a natural language query. It would return the lines to edit for edit mode.

ailly --find hello.js --prompt "the method whizbang"

Haiku prompt:

Human: The text of hello.js
Assistant: ...
Human: Examples of tree sitter scripts
Assistant:
Human: Write a tree sitter script for this question: the method whizbang

Possible reply:

(
            (comment)*
            .
            [
                (function_declaration name: (identifier) @name (#eq? @name "{whizbang}"))
                (assignment_expression
                    left: (identifier) @name (#eq? @name "{whizbang}")
                    right: (arrow_function)
                )
            ]
            )
            @fn

Then execute this against hello.js and get line numbers.
