federal text fix: a subsection heading was running straight into the text it heads (282,636 places in the Code, e.g. 26 U.S.C. 1(a)); headings now sit on their own line. Same 60,433 sections, same schema, text only.

add federal law: the whole United States Code, 60,433 sections across all 53 titles, measured (OLRC USLM XML bulk, release point Public Law 119-103, 2026-09-02). Notes/annotations excluded from text; source credit, positive-law flag and repealed/omitted status kept in extra. Card regenerated with a federal row and a per-title table.
