Scope: US Federal Register (daily journal of the federal
government) via GovInfo's cross-collection search endpoint.

Federal Register contains agency final rules, proposed rules,
notices, and presidential documents (executive orders,
proclamations). Continuous publication since 1994 in GovInfo.

Endpoint:
    POST https://api.govinfo.gov/search
    (query: collection:FR AND {your_query}
            [AND publishdate:range({from},{to})])

Args:
    query: free-text query (e.g. `"EPA methane rule"`,
           `"section 230"`, `"executive order 14023"`).
           Combined with `collection:FR` under implicit AND.
    date_from / date_to: YYYY-MM-DD publish-date filter.
    limit: pageSize (GovInfo cap 100).
    offset_mark: pagination cursor from previous response's
                 `next_offset_mark`; `"*"` starts from newest.

Returns dict with `results` — each row has `title`, `package_id`
(e.g. `FR-2024-12-27`), `granule_id` (per-document id),
`date_issued`, `government_author[]`, download URLs
(`download_txt_url`, `download_pdf_url`, `download_mods_url`
for XML metadata), `original_url` back to
www.govinfo.gov/app/details/. License: US Public Domain.
Requires `US_GOVINFO_API_KEY` for signed ceiling (1000/hr).
