* Numfmt: one built-in format table, no dead render arms, fewer allocations (#817) S1: the built-in format table lives only in gridcraft-xlsx (file formats do not depend on numfmt); numfmt's unused copy and its exports are removed, xlsx gets tests pinning its lookup rules. S3: drop the render_number arm that printed what the fallback prints; literal text is appended to the output instead of built as a String per call. O3: render_number keeps pieces, text-before and literal replacements in one buffer (Parts), fill_int writes digits left to right, Section stores the date flags (sub-second digits, calendar, AM/PM) computed at parse time, render_date writes into one buffer. O4: significant_digits formats into a stack buffer; format_general_fit re-rounds the 15 digits per width into reused strings. An equality test compares format_value, TEXT() and format_general_fit with digests recorded from the previous implementation.
