Bug: `n(-1).` failed to parse — the tokenizer produced op `-` followed by number `1`, and dl-pp-parse-arg expected a term after seeing `-` as an op (and a `(` for a compound) but found a bare number. Users had to write `(- 0 1)` or compute via `is`. Fix: dl-pp-parse-arg detects op `-` directly followed by a number token (no intervening `(`) and consumes both as a single negative number literal. Subtraction (`is(Y, -(X, 2))`) and compound arithmetic via the operator form are unaffected — they use the `-(` lookahead path. 2 new parser tests: negative integer literal and subtraction compound preserved.
