scholar 1.0.1

• Google Scholar refuses a script in more ways than a failed request, and each one is now named: a sign-in redirect, a captcha page served with HTTP 200, a 403, a dropped connection, or a rate limit. A refusal is reported once per session with its real cause instead of "Cannot connect to Google Scholar. Is the ID you provided correct?" (2026-10-29, Thu, jkeirstead#123)
• send browser-like headers on every request, back off exponentially with jitter when rate limited, honour Retry-After in both its forms, and bound the total waiting per process with scholar_retry_budget (60 seconds by default), so a blocked check fails fast instead of spending its time on delays (2026-10-29, Thu, jkeirstead#123)
• author search now requires a signed-in session, so get_scholar_id() and search_scholar_ids() are deprecated for anonymous use and say when Google refused rather than finding nothing; search_openalex_authors() answers the same question from OpenAlex with no session, and a fractional max_results is rounded rather than sent as a request OpenAlex rejects (2026-10-29, Thu, jkeirstead#91)
• set_scholar_cookie() and the scholar_cookie / scholar_cookie_file settings present a session exported from a browser. It is sent as a cookie, so it merges with Google's own and survives the redirect to the sign-in host, and it is never sent to a mirror that is not a Google host (2026-10-29, Thu, jkeirstead#91)
• add get_citing_articles(): the works citing a publication, with venue, year and their own citation counts (2026-10-29, Thu, jkeirstead#4, jkeirstead#107)
• add get_h_index_history(): the h-index year by year, rebuilt from each publication's citation history and cached so the expensive pass happens once. It works for a profile whose cited papers all fall in one year, and a refused history is no longer cached as a paper that was never cited (2026-10-29, Thu, jkeirstead#73)
• get_profile() reports every colleague rather than the twenty the sidebar shows, and no longer mistakes a profile's sort-menu links for coauthors (2026-10-29, Thu)
• get_journalrank() is deprecated and downloads nothing: SCImago serves a JavaScript challenge to scripts and its table carries no published licence. The help page points at OpenAlex for journal metrics (2026-10-29, Thu)
• new settings, each falling back to an environment variable of the same name in upper case, for hosted deployments and CI: scholar_user_agent, scholar_accept_language, scholar_request_delay, scholar_retry_delay, scholar_retry_max_delay, scholar_retry_budget, scholar_timeout, scholar_cookie, scholar_cookie_file and scholar_openalex_mailto (2026-10-29, Thu)
• the README and the vignette say what to do when Scholar refuses a request, list every setting the package reads, and warn which endpoints a server cannot reach (2026-10-29, Thu, jkeirstead#123, jkeirstead#91)
