Render LLM Helpers

[sh-rp]

We could could also output some additional info the user can use for prompting, example:

When rendering endpoints, let's dump useful LLM information into a text file that may be used for prompting (manual).
Ideally for each rendered endpoints we have a path fragment of openAPI spec that contains the following

only GET operation
parameters but dereferenced
actual response that we picked
in the response the schema should be de-referenced (but maybe only to the 2 nesting level)
examples should be kept

let's render using yaml. this is what LLM will understand

if we detected parent endpoint let's give path to it.
