Working with OpenAlex Snapshots — Moved to openalexSnapshot

Snapshot functionality has moved.

The full OpenAlex snapshot workflow — downloading the official Parquet snapshot, building ID lookup indexes, and extracting records by ID — is now part of the openalexSnapshot package.

Please install openalexSnapshot and refer to its documentation.

# Install openalexSnapshot (once available on r-universe):
pak::pak("openalexSnapshot")

snapshot_to_parquet(), build_corpus_index() and lookup_by_id() are no longer part of openalexPro in any form. They previously remained as stubs that raised an informative error, but an exported stub masks the real function whenever both packages are attached – library(openalexSnapshot); library(openalexPro) made the stub win and error. Call them as openalexSnapshot::build_corpus_index() and so on.
