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.

// A tuple type (`Tuple(i32, i32)` at a type-demanding site like `size_of`) must
|
|
// list only types. A non-type
|
|
// element — here the `1` in `Tuple(i32, 1)` — is rejected with a user-facing
|
|
// diagnostic instead of silently fabricating an `i64` field for that slot.
|
|
// Regression (issue 0067).
|
|
// Expected: a clean "tuple type element is not a type" error at the `1`; exit 1.
