agra 0bc8005b99 fix: diagnose ?(?T) tuple-payload mismatch instead of malformed IR (issue 0165) ...

In type position (T) is a 1-tuple (specs.md:843), so ?(?i64) is
optional(tuple(?i64)); assigning a bare ?i64 had coerceToType classify
.none and pass the value through, then optionalWrap built a corrupt
insertvalue that aborted the LLVM verifier. After coercing toward an
optional's child, verify the coerced type equals the child type
(stmt.zig decl-init + coerce.zig .optional_wrap); on mismatch emit a
located diagnostic (tuple-specific note only when the child is a tuple).
formatTypeName now renders tuples as (x: i64, y: i64).

Regressions: optionals/0911 (nested optional via alias, round-trip),
diagnostics/1195 (the mismatch diagnostic). Updated diagnostics/1101 +
protocols/0414 goldens for the improved tuple type-name rendering.
Verified by 3 adversarial reviews. Filed adjacent bug 0171 (?any child
not canonicalized).
