docs-wide @ref for menitoned methods and structs.

## Issues

Currently we use `@ref` to link between docs page sections etc. but can also be used for documented functions. deploy this docs-wide.

## Possible solution

Seems like a good use case for claude skill `doc-refs`.

Start by reviewing the repository documentation for existing @ref links between page sections and for documented functions and structs. Apply the @ref treatment docs-wide, then verify that the documentation consistently links mentioned methods and structs.
