Function insert_document_statement 

pub fn insert_document_statement(
    table: &str,
    document: &TextDocument,
) -> SqlStatement

Build the INSERT half of the FTS delete-then-insert upsert.

table must be a trusted, sanitized table name because SQL identifiers cannot be bound as parameters.

This statement alone leaves rowid_map_table out of date — pair it with insert_document_map_statement (or use insert_document_statements for the order-safe combination) so the sidecar tracks the new rowid.
