Federal Register documents on public inspection (pre-publication) API

The Federal Register public-inspection feed: documents on display BEFORE official publication — an early-warning signal for incoming rules/notices. Normalized with document number, title, type, filing type, filed/publication dates and agencies, plus by-type and top-agency tallies. Distinct from existing fedreg search/document/agency endpoints. Answers 'What rules are about to publish?', 'Which agencies are filing right now?'.
