Rewrite specs.md tuple/failable/pack/UFCS/grammar sections to the new syntax, update readme.md, and refresh stale tuple references in example header comments. Also fixes two pre-existing doc inaccuracies surfaced in review: drop the value-discarding `;` in the tuple-return examples, and correct the §13 function-type grammar production (optional param list + optional trailing `!` channel). Optional semantics unchanged. current/CHECKPOINT-LANG.md logs the cutover.
