/**
 * Dispatch a built-in formula function by name, evaluating its arguments through
 * `ev`. An unknown or misused function returns `#NAME?`/`#VALUE!` so the calling
 * conditional-format rule simply does not apply — Ream never guesses.
 *
 * @param name  The upper-cased function name (e.g. `SUM`, `VLOOKUP`).
 * @param args  The unevaluated argument expressions.
 * @param ev    Evaluator for one argument (closes over the context + shift).
 * @param ctx   The evaluation context (grid access, defined names, date system).
 * @param shift The per-cell shift (used by no-arg `ROW`/`COLUMN`).
 * @returns The function's result value.
