feat: export cog_basket_resolution() and cog_basket_unresolved()

Sidecar accessors for basket-mode results. cog_basket_resolution()
returns the full resolution tibble (drops candidates list-col by
default for readable printing). cog_basket_unresolved() filters to
ambiguous/no_match rows for iterative refinement.
